I am the man you thought I couldn't be

I am the man who once couldn't see

I am going to be a success

I will always try my best

I am who I wasn't in the past

I'm a better person and I hope that'll last

I'm in college on the way to better

I will succeed while spelling out every letter 

Who am I? Right now you may say 

I hope that everyone will know someday 

I hope to effect the world in the greatest way 

Giving back every favor ever service as I pray 

WHO AM I?
