The brain can be developed just the same as the muscles can be developed, if on will only take the pains to trainthe mind to think.

The cheerful mind perseveres and the strong mind hews its way through a thousand difficulties.

If you assume you haven't learned anything yet, there's no reason your playing can't stay dynamic all your life.

My life is not a political campaign. I just write about what is on my mind. I just play whatever I feel like playing. Whatever is in my soul at the time is what I want to do. I have, thank god, enough people who are still interested in what I am doing so that I can go out and keep doing it.

I try not to look back. I'm looking forward. I'm worried more about what I'm going to do next week than I am what I did last week. There are too many things to do. Looking back is for everybody else.

The empires of the future are the empires of the mind.
