everyday internal conflict

Starting to feel tired of where i am right now. I feel like i have more potential and a lot to offer but i cant because I feel constantly confined to this small part only. Its like a curse that sticks to me i can't get away from it no matter what happens even if i do get better. The desire for respect, acknowledgment and discovery. I am just as determined as everyone, just as dedicated, patient, and persistent. Yet I cant help but still feel like I'm nothing and like i will never get anywhere better if i keep staying where i am right now. The only person that can help this situation is me. No one else can do it, no one else can help, only I can make myself known. And i know exactly how i can do it, i know exactly how to get where i want to be and I've had the chance so many times but every time i cannot help but lose it and mess up. Something inside me causes me to mess up every time a new chance comes along. Its like some kind of fear or nervousness inside that's holding me back. If I am ever to achieve my goal then I'm going to have conquer whatever is holding me back. At least once everyday I think about this problem and my situation. One day though before the year ends i can promise that i will conquer that fear, that nervousness and I will achieve my goals.
