Why not start living the crazy-startup-founder lifestyle today? That's what I'm trying to do. [1]The time I spend at my current job is like sleeping to me. It's time during a 24 hour period that I just plain will not get back. I have to do it or I will die.
But the hours I spend not sleeping are hours that I spend reading, and hacking, and writing, and more reading, and more hacking.
As much as I'd prefer the weather (and the availability of coffee) in the Bay Area to the weather in Phoenix, I can't make the move happen right now, so I'm just doing the "crazy hours" thing anyway :)
[1]: I just want to clarify that I don't mean I'm slacking off at my job, if anything, being in "work" mode 100% of the time, as well as having a passion for learning new stuff has benefited my employer. When I say "sleeping", I just mean something that I don't have a choice about doing.
