How to get rid of unrealistic goals
Determine if your goal is based on external factors.
You should come up with goals that are based on yourself and your own abilities. That means that you alone are responsible for your success or failure.
If you base your success on the actions and abilities of others, you risk failing not because you weren't good enough, but just because someone else was better. This will frustrate you and you may end up quitting your goal.
