Of course, as our host points out in Beating the Averages (http://paulgraham.com/avg.html), "If you do everything the way the average startup does it, you should expect average performance. The problem here is, average performance means that you'll go out of business."

Which, if you're one of these "overachievers", increases the chance the start up that hires you, at least early enough that stock options might even vaguely maybe be worth something someday, will fail. This has happened at several that I've worked for, they died hard after I was purged.
