Astro Teller on creativity and the fool's mindset.  

“The fool loves side quests and often goes looking for them. Push down your focus and see how high you can turn up your curiosity. Yes, you have to file your taxes on time. But don’t let that become an excuse to get stuck in largely focused, goal-chasing mode. You will get more in life and you will have more fun getting it if you are open to side quests.”
