I'm very proud to be black, but black is not all I am. That's my cultural historical background, my genetic makeup, but it's not all of who I am nor is it the basis from which I answer every question.

I paint what I like, when I like, and where I like.

It is error only, and not truth, that shrinks from inquiry.

To be human is to be flawed, but it is also to be capable of great change.

I don’t like to be told what to do. I like to make my own decisions.
