With all the great resources available to improve our lives, it's surprising that most people still struggle to love work. Why is that? In my opinion, it boils down to one simple problem: Most people are in the wrong jobs.

When something doesn't feel right, it's not because you're not smart enough or not good enough. Often it's because the job you're in isn't the right fit.

Here are six signs that your job isn't the one for you:

1. You feel like you're working insane hours but can never catch up.

If it's taking you longer than others to complete tasks, you might not be in the right role. That doesn't mean you're slow or have no redeeming qualities (although it can often feel that way). It just means that your skill set probably doesn't line up with that specific position.

2. You're getting feedback that suggests you change aspects of yourself that would fundamentally change who you are.

When the feedback you're getting means changing something about who you are, it's a clear sign that you're not the right person for the role. That doesn't mean you should change yourself to fit the role, however! It just means you should commit to finding a better role - either at the same company or at a different one - and letting someone else who is a good fit take over your job.

3. You can't seem to meet expectations no matter how hard you try.

This is related to the sign above. If you're putting in every ounce of effort into your role and still not measuring up, it could be a clear sign that you're not the right person for that job.

4. You rarely feel excited about the work that you're doing.

Although no one loves their job every minute of every day, it is important that you take pride and joy in it - at least occasionally. If you can't remember the last time you felt excited about the work you were doing, you're probably being drained in ways you don't even realize. Assess your emotions and see if you're actually miserable at your job. If so, it's time to move on and find another one.

5. You don't feel a personal connection to the impact that your work has on other people or in the world.

If you don't feel a personal connection to the impact that your work has on other people or in the world, that might be because you know, on some level, that you're not doing what you're meant to do. In that case, it's worth spending some time to figure out what your purpose is.

6. Your motivation for work is rooted in trying to prove your worth to those around you.

If your motivation isn't coming from within, you've got some thinking to do. Are you really just trying to please or impress the people around you? Sure, you might end up with an impressive title or two on your resume, but you'll probably be worse off in the long run. If you're not intrinsically motivated, you'll most likely burn out before too long, which will impact you long after your job is over. Instead of trying to force a role to fit because of outside pressure, focus on what works for you and your personal needs and goals.

A job that is the right fit should feel challenging (in a good way) but not so hard that you continually struggle to achieve success. When it's obvious that your work situation isn't working out, it's important to recognize the situation for what it is and plan to move on. Job-hopping is now the new norm. Staying in a job that isn't the right fit will only give you more grief. So be grateful for the lessons learned, tackle change, and fight for work you love. That's the true path to great success.
