All of my friends who have younger siblings who are going to college or high school - my number one piece of advice is: You should learn how to program.

If we want to have the biggest impact, the best way to do this is to make sure we always focus on solving the most important problems.

People can be really smart or have skills that are directly applicable, but if they don't really believe in it, then they are not going to really work hard.

I don't have an alarm clock. If someone needs to wake me up, then I have my BlackBerry next to me.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk. Companies are set up so that people judge each other on failure. I am not going to get fired if we have a bad year. Or a bad five years. I don’t have to worry about making things look good if they’re not. I can actually set up the company to create value.

You grow more when you get more people's perspective.

People developed planes first and then took care of flight safety. If people were focused on safety first, no one would ever have built a plane.
