You can click through to read more, but the highlight for me was: "So, Paul Graham, what I liked about him was he’s always been a complete non-conformist and has gotten away with it, not because his parents had money or he was privileged, but because he didn’t care and he took risks and he just followed what he wanted to do. And that’s sort of the end of this book. That’s like the ultimate thing."
