I had some success in my life and got to met pretty successful people, the Bill Gates and Steve Jobs of different fields. I had never met any of them wanting to "save the world". Saving the world does not make sense. It is too diffuse, too abstract. When you met someone like Bill Gates, you met someone who has traveled to Africa and seen people suffering, children and women spending hours a day to get water (that they can't use for other things like learning). Children dying of diarrhea(because of the water), Parents dying because of H.I.V and creating millions of orphans. You see, this is not abstract but concrete problems. You can actually do something today to improve other people's lives, today. The world is full of them. We love problems because we can solve them, and this is not a delusion. It is a gift. You can improve people's lives in lots of ways. Geeks have the opportunity to improve millions of lives. Helping people is incredible rewarding, just by itself.
