Great advice. One of the secrets is to do something you believe in, which is why having a startup is so good. The other is to have a close deadline, that work's for me anyway. A peppering of exercise and plenty of sleep also help. I don't believe in all this 'sleep hack' stuff - just get 6 to 8 hours on a regular basis, but that's a whole separate discussion.
