Think about this: you just spent a day at work, and you’ve thought all afternoon about how you want to tackle a goal that’s been on the back-burner all week. As the day wears on and you make your way home, you tell yourself over and over like a broken record how you need to put your head down, so to speak, and finally get around to doing that one thing you need to do.

You get home, put your bag down, and… fast-forward a few hours. Before you know it, it’s time for bed.

What happened?

Well, you lost all the energy you needed; your mind effectively gave up before you even started.

A lack of energy can go beyond feeling physically tired. It can permeate into what’s known as “mental tiredness.” And it’s a real thing, affecting almost everyone for various reasons. But what if I told you it’s completely possible to tackle it? All it takes is identifying some of the sources of your lack of energy and finding ways to work with it.

Let’s go through the lack of energy causes and how to fix them.

1. An Unfulfilling Job

Everyone knows they spend at least eight hours a day at their job generally five days a week. If you think about it carefully, though, you’ll realize that these 40 hours a week translates to about 88 full days a year you’re at your job.

We’re talking 88 straight, 24-hour days worth of work in a year. That’s about 25% of your entire existence, not including sleep, spent at your job. That’s a lot of time.

So if your job is unfulfilling to you, no wonder your mental fortitude takes the biggest beating.

Unfulfilling can also mean several things:

  • You hate your job.
  • You’re not learning anything.
  • You dislike the job but get paid well.
  • You’re bored at work.

There are many more situations, so inevitably the question gets asked: How do I know if my job is unfulfilling?

Do you feel drained? Do you dread going to work each morning? Do you often think about what you’d rather be doing when you’re at work? If you can answer yes to any of these questions, you probably need to reconsider your career choice.

Why? A recent study found a direct link between job satisfaction and mental health[1]. Those who reported less satisfaction with their jobs suffered from higher bouts of depression and sleep difficulty.

How to Fix the Problem

An unfulfilling job is an incredibly common problem faced by people around the world. Some people don’t know what their dream job is, while others don’t have the skills to get into their dream job when they want to.

The first step would be identifying jobs that would feel fulfilling. Make a list of your skills and the topics you enjoy learning. Which jobs would those things serve?

If you already know what you want to do but don’t currently have the skill set for it, take small steps to get where you need to be. Take an online class, find a mentor, or go back to school (if you have the time and the means). Is there a related job you could do that could help you build the right skills? If so, start there.

2. Overwhelming Task List

Got stuff to do? Great, so does everyone else.

Got a lot of stuff to do? You’re not alone.

Imagine this:

You open your task list, ready to start checking off items. You sip your coffee, sit down, and almost fall backward off your chair when you realize you’ve got about 18 things to do in the next five hours.

And this may be a contributing factor to your lack of energy. Feeling overwhelmed is a quick way to feeling burned out. When we feel like we have too many things to do, we tend to freeze (or have what’s called workload [2]) because we don’t know what to tackle first.

This feeling continues, and before you know it, the entire day has gone by and you’ve filled your time doing everything except what you need to do; in other words, you do nothing of importance.

Then, as the days turn into weeks, and the weeks turn into months, you come to the harsh realization that you didn’t achieve all the things you set out to do. It’s a defeating feeling when you don’t think you’re capable of achieving much.

The defeating attitude is a vicious cycle, too — you start by feeling overwhelmed, don’t do anything about it, then waste time before feeling defeated — and a fast track to mental burnout.

How to Fix the Problem

Split up your list. If there are too many things to do in one day, move items to your “tomorrow” list, or even to a “weekend” list. Make your list achievable by writing a time limit next to each item so you can imagine how long a full list will take to complete.

3. Saying “Yes” Too Often

“Hey, want to go catch a movie?”

“Want to come over?”

“Can you pick me up from the airport?”

“Want to grab dinner?”

If you’re a yes person, no doesn’t exist in your dictionary. The problem is, it should.

If you’re spending all your time doing everything everyone else wants but no time doing the things you want, you won’t get much accomplished in your life. Just like in the above example, when you realize months later you didn’t get very far, you tend to become defeated, which ultimately leads to feeling mentally exhausted.

The good news is you can become a “no” person whenever you feel like it, and in turn, start accomplishing the things you want. But if you’re used to saying yes, it’s not an easy thing to suddenly switch gears.

Being able to focus on yourself gives you an incredible sense of accomplishment and in turn, helps your mental state; it’s OK to put yourself first.

How to Fix the Problem

Saying no will likely be difficult at first if you’re used to always saying yes. Start by trying to say no to one thing each week. If you’re worried that saying no will affect how the other person thinks of you, this may be a problem related to self-esteem more than anything else. It may be time to do some self-reflection to see why you want to please everyone by refusing to say no.

4. Lack of Hobbies or Passions

Hobbies and passions are what fuel us to do great things. In many cases, they lead you to your life’s purpose. At worst, they give you an incredible sense of fulfillment and a source of happiness in your life.

When your job gets tough, it’s important to have an outlet to focus on. When your job isn’t aligned with your passions or purpose, it’s especially important to have an outlet to apply your skills and excitement. Having something to put your attention towards can help provide your life with direction and meaning.

In a roundabout way, focusing on hobbies or passions can ultimately improve your work or family life.[3] All this is to say: you’re a much better person, especially mentally, when you apply yourself to things that interest you.

When you don’t have any source of motivation to work towards, you become tired of dealing with the mundane things that life throws at you. And then you become annoyed and yet again, defeated. This frustration can lead to mental exhaustion if it continues long-term.

How to Fix the Problem

If you haven’t made time for a hobby in the past, it’s time to carve out some “you” time each day. Take an hour in the morning or evening to put toward something you enjoy doing. If you don’t have a favorite hobby, start trying things. Say yes to joining that tennis match with your friend or sign up for that free pottery class in town. You never know what you might end up enjoying.

The Bottom Line

Feeling tired from a lack of sleep is one thing. Feeling tired because work isn’t fulfilling, you have no hobbies or passions, you stretch yourself thin, or you feel overwhelmed is another thing.

It’s important to know the difference and work towards defeating the lack of energy you may be feeling.

The four sources listed above are a starting point for you in your quest. There are many more, but these comprise some of the most common. Once you’re able to identify the specific problem in your life, you can get yourself back on track and feel more energetic in your daily life.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Orthopedic doctor, rheumatologist, or physiotherapist depending on cause.

What to tell the doctor

  • Write which joints hurt, swelling, morning stiffness duration, fever, injury, and walking difficulty.
  • Bring X-ray, uric acid, ESR/CRP, rheumatoid factor, or previous reports if available.

Questions to ask

  • Is this injury, osteoarthritis, rheumatoid arthritis, gout, infection, or another cause?
  • Which exercises, supports, or lifestyle changes are safe?
  • Do I need blood tests or X-ray?

Tests to discuss

  • Joint examination and range of motion
  • X-ray when chronic arthritis or injury is suspected
  • ESR/CRP, uric acid, rheumatoid tests when inflammatory arthritis is suspected

Avoid these mistakes

  • Do not ignore hot swollen joint with fever.
  • Avoid repeated steroid injections/tablets without a clear diagnosis and follow-up.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Severe symptoms, confusion, fainting, breathing difficulty, chest pain, severe dehydration, or sudden weakness need urgent medical care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?

  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Causes of Lack of Energy

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
