When you are studying medicine people expect a lot from you.
The fear of not meeting these expectations is also very high.
Stop for a moment and think about this.
Failure is not the opposite of success in medicine.
The fear of failure is part of the process of studying medicine.
So think about this.
What did you actually learn from the mistakes you made in the past?
Are you using those mistakes to learn. Are you just feeling sad, about them?
If you were not afraid of failing would you study in a way?
Every doctor you look up to was once a student who did not know all the answers.
Tell me what you think. How do you deal with the fear of failure when you are studying medicine?
