I would like to say that trust yourself is very important.In order to have a strong conviction in oneself to becomes better,one has to first love himself in order to have such confidence.
There is nothing you can do if you don’t have the self-confidence.I believe you’ve seen the movie KungFu Panda,Bao does not give up no matter how hard it is,and becomes a KungFu master finally.This is just because of his persistence believes in himself.Hence,we have to trustourselves.
