The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on.

我不后悔我做过的事，我后悔的是有机会时没有做的事。

Life is about taking chances, trying new things, having fun, making mistakes and learning from them.
