How to finally live up to your own expectations

I think you need to evaluate what you are capable of and what your expectations are. Instead of making it complicated, sometimes the simple solutions are the right way to go. Try saying to yourself," I am a good athlete and student. I am going to do the best I can. Instead of my expectations being about achieving certain awards or scores, my expectations are to advance in what ever Im doing and learn more." Be patient! and don't think that you cant achieve your high expectations! you can:)

I've had this exact problem. I used to get really anxious about school and all the work that goes along with it, especially my grades. What I learned was that YOU come before your grades. If you're beating yourself up, then just tell yourself that you're only human! Nobody, even yourself, can expect more out of you than you are capable. Give it your all and remind yourself to relax once in a while :)
