What you'll wish you'd known

Paul Graham is an essayist, programmer, and programming language designer. In January 2005 he wrote a speech entitled "What you'll wish you'd known" to be given at a high school, however the authorities there vetoed the invitation. In his speech, Paul says "I'll start by telling you something you don't have to know in high school: what you want to do with your life."
