I find it hard to believe that he had no stress. Startups are stress engines. Things go wrong, usually under deadline. And that causes stress. The stress can be managed and "evolved" people don't let it control them, but stress exists for a reason. Without it, we would probably not be here as a species.<p>What about, for example, the time he spent many months rewriting his site in Rails and then, after traveling far down that road, decided to scrap the rewrite and go back to PHP? If that didn't cause he any stress, then he must be more robot than man. ;-)
