I don't have any particular advice. I've been very lucky to join a few companies that were on the run up at the time but I never really knew at the time that they were going to be successful.
I just think blindly pursuing passion to the exclusion of profit will leave most people happy (or not) but impoverished and some people happy, lucky, and wealthy.
It was really just a tongue in cheek comment. I think Paul's advice is inspirational but it should be checked with a healthy dose of reality.
