Sometimes in life, it's time to stop what you've been doing and move on to the next thing. Hopefully, it's because you've explored the depths of your current activity and have mastered the whole arena. It can be a powerful feeling to know you've learned something so well, and can walk away at the top of your game. At other times, it's not your choice to walk away. You may feel you have more to learn and accomplish where you are.

Granted, it's not always up to you to determine when it's time to make a change. Perhaps you don't want to leave, but all parties feel a new beginning is the best decision for everyone involved. Whatever the reason for departure, it's often important to depart the right way, without burning bridges and always appreciating the experience.

No need to be mad it's over or sad the journey can't continue. You can easily grateful for the opportunity and take stock of everything you learned.

Here are tips on how to know when the time is right to move on:

1.     The enthusiasm is gone.

When you first embark on a new project, the energy and enthusiasm you feel can be thrilling. You're attacking a new challenge at full force, eager to dive in and make a difference. When you succeed, the endorphins explode in your body. You feel like you can achieve anything you set your mind to. Eventually, however, the enthusiasm fades. Some of this is a natural part of growing. But when your enthusiasm wanes too much, it's likely time to move on to something else. If you stay, you risk becoming resentful of the current position, and risk your reputation if your best effort lags.

2.     You stopped learning.

One of the most important motivators in your personal journey is constantly learning. It's critical that you feel a desire to get better every day. If you can't learn from your experience, what are you getting out of it? How will it help you make tomorrow better? If you've learned all there is to learn, or if you can't stand the thought of learning more about the same thing, it may be time to leave the past and forge into the future.

3.     Feedback has dried up.

Perhaps colleagues and supervisors assume you know everything already, so they don't bother trying to teach you. Maybe you've stopped seeking it out, out of boredom or indifference. Or perhaps your attitude towards feedback has changed, and where you used to be receptive to it, you no longer are. Whatever the reason, you either need an attitude adjustment, or you need to remove yourself from a toxic situation and move on to the next thing.

4.     It's not fun anymore.

Fun should be a part of your daily life, both personally and professionally. Unfortunately for many people, it's not, particularly in their professional lives. It can be awfully difficult to summon the energy and courage to get up every day if all you're facing is dread. If something makes you that unhappy, it's time to consider doing something else. No one deserves to be miserable.
