Here’s my challenge. Right now, put aside 100 hours over this summer. Do it right now, in your head. Put that time aside. 100 hours. 8 hours a week for the next 12 weeks. One hour a day, or one working day a week. It’s one summer out of your entire life, it’s nothing. Okay, you’ve got that 100 hours? Now for the next two days, go to talks and start conversations with people you don’t know, and choose what to spend your 100 hours on. I guarantee that everyone in this room can produce something or has some special skill, and maybe they’re not even aware of it … Because when you contribute, when you participate in culture, when you’re no longer solving problems, but inventing culture itself, that is when life starts getting interesting.
