Be an enzyme - a catalyst for change. As a slogan, I don't know if that's ever going to be right up there with Ich Bin Ein Berliner, or “I Have A Dream,” but there's a lot of truth to it.

We have technology, finally, that for the first time in human history allows people to really maintain rich connections with much larger numbers of people.

When you don't know what to expect, prepare for the unexpected.

You should pursue your passion. If you're passionate about something and you work hard, then I think you will be successful.

You have to really believe in what you're doing, be passionate enough about it so that you will put in the hours and hard work that it takes to actually succeed there, and then you'll be successful.

Whatever future you're building, don't try to program everything.

It is not really work if you are having fun.
