The thing I really care about is the mission, making the world open.

The biggest risk is not taking any risk.

Don't discount yourself, no matter what you're doing. Everyone has a unique perspective that they can bring to the world.

I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress.

Move fast, take risks, it's okay to try big things you're better off trying something and having it not work and learning from that than having not done anything at all.

The biggest risk is not taking any risk... In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

The future has a way of arriving unannounced.

Colors express the main psychic functions of man.

Night begins to muffle up the day.

Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.

I love you more than the pool hall, but not as much as football.

If you observe well, your own heart will answer.

A few times in my life I've had moments of clarity where the silence drowns out the noise and I can feel rather than think.
