Paul Graham said this quote

There are few sources of energy so powerful as a procrastinating college student.

~ Paul Graham

You can't distinguish your group by doing things that are rational and believing things that are true. If you want to set yourself apart from other people you have to do things that are arbitrary and believe things that are false.

~ Paul Graham

At every period of history, people have believed things that were just ridiculous, and believed them so strongly that you risked ostracism or even violence by saying otherwise. If our own time were any different, that would be remarkable. As far as I can tell it isn't.

~ Paul Graham

The recipe for great work is: very exacting taste, plus the ability to gratify it.
