Oh, come on. Wasting your life == working as a Blockbuster video clerk, assuming that you don't have an art career or something else on the side.
Also, I take it you don't live in SV? 99% of the startup activity around here is downright moronic. Stupid money chasing stupid ideas.
Yes, you might walk with that startup swagger. I happened to be in South Park on Friday around lunchtime, and watched all the cool kids strutting in the sunny afternoon. I work for a megacorp, and it's hard not to envy them.
I'm not arguing that megacorps are better for everyone, but it's nowhere near a waste of your life. They operate on a scale that most startups can barely comprehend. The stuff you can learn and do there is serious business.
