"I hated poverty. Poverty is more of a choice than anything else, and I can change that (poverty). It depends upon how hard I want to work, and I decide that I would change it." Dr. Ben Carson 

You can be anyone whether it is a doctor, lawyer, ETC.  All you have to do it work hard for it. Be a committed person into doing something. Dr. Ben Carson thought he was dumb in school and his friends did too. But, little did they know that he had intelligence inside of himself just that he did not use it. And now he is a surgeon that performs surgeries on conjoined twins. Everyone has the potential in doing something. For example if you want to pursue your future life goals then you have to work hard for it. Don't lower your self-esteem everything will be ok if you put all your effort into accomplishing it.
