Paul Graham's new essay on "How Not to Die"

Paul Graham's latest essay is about "How Not to Die", in reference to technically-oriented "startups". Paul says, among other things:

So I'll tell you now: bad shit is coming. It always is in a startup. The odds of getting from launch to liquidity without some kind of disaster happening are one in a thousand. So don't get demoralized. When the disaster strikes, just say to yourself, ok, this was what Paul was talking about. What did he say to do? Oh, yeah. Don't give up.
