I came to similar conclusions. Seriously attempting a startup would be very time-consuming and stressful. The original poster doesn't understand why this is, because he miscalculates the execution, production, marketing, and team risks involved in his project. But unless he has a serious financial safety net, he will soon start burning through the limited resources of his money, time, and energy, which could hurt his social development.

Personally, working at an early-stage startup has a much higher expected value for me than trying to run my own thing.
