I think this also explains why most startup founders are the age that they are. The further my 30th birthday recedes into the past, the more the "success is mostly luck" hypothesis rings true. I'd be much more reluctant to roll the dice now than 10 years ago. (On a related not, fame and fortune seem less appealing now as well.)

You must be well off? Fortune seems far more important to me now that it's rather late in the day to be doing anything about it ... [fame can hang for all I care].

Hah, far from it. Being wealthy would be great but having seen several acquaintances sacrifice health, relationships, and happiness in pursuit of that goal, I've come to the conclusion that it's simply not worth it. I side squarely with the Mexican fisherman, you might say.
