There's nothing wrong with things taking time.

I made 5,127 prototypes of my vaccum before I got it right. There were 5,126 failures. But I learned from each one. That’s how I came up with a solution. So I don’t mind failure.

What I've learned from running is that the time to push hard is when you're hurting like crazy and you want to give up. Success is often just around the corner.

A deep soul lives in conscious awareness of eternity, not simply today.

If anything I consider myself an anarchist.

Never be embarrassed by the things you cannot do. Be embarrassed by the things you can do and don't do well.

I was on the playground all night. I ain't never go to parties or nothing. I'd get out of school at 3 and be out there playing until one in the morning with one streetlight. For real.

When someone says 'I'm so disillusioned', I say 'Congratulations! You've lost another illusion.'

Finally I am becoming stupider no more.

You don't want lopsided government. You don't want one side running roughshod over the other.
