News in general doesn't matter most of the time, and most people would be far better off if they spent their time consuming less news and more ideas that have more lasting import.

Our problem wasn’t that it blew up and was impossible to scale, but there were some bad choices made. One of the biggest lessons time after time was to focus. Do fewer things.

When you’re obsessing about one thing, you can reach insights about how to solve hard problems. If you have too many things to think about, you’ll get to the superficial solution, not the brilliant one.

Take care of yourself: When you don't sleep, eat crap, don't exercise, and are living off adrenaline for too long, your performance suffers. Your decisions suffer. Your company suffers. Love those close to you: Failure of your company is not failure in life. Failure in your relationship is.

Hard things are valuable; easy things are not so valuable. Reaching the mountaintop is rewarding because it is hard. If it was easy, everybody would do it.

The things that keep nagging at you are the ones worth exploring.

Change the world. Build a business. Have fun.
