When you grow up, you tend to get told that the world is the way it is, and your life is just to live your life inside the world. Try not to bash into the walls too much. Try to have a nice family life. Have fun, save a little money. That's a very limited life. Life can be much broader, once you discover one simple fact, and that is everything around that you call life was made up by people who were no smarter than you. And you can change it. You can influence it. You can build your own things that other people can use. Once you learn that, you'll never be the same again.

Have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

Unless you've a lot of passion about this, you're not gonna survive. You're gonna give it up.

I think it's half the battle right there.

Our goal is to make the best devices in the world, not to be the biggest.

I have a great respect for incremental improvement, and I've done that sort of thing in my life, but I've always been attracted to the more revolutionary changes. I don't know why. Because they're harder. They're much more stressful emotionally. And you usually go through a period where everybody tells you that you've completely failed.
