That's a bit dicey - the kind of thing that may work delightfully well and be justified and appropriate in maybe like 1% of cases, and be excessive and likely to backfire horribly in the other 99%. But then, there's the issue of having to be like that pretty much all the time for it to be really believable and effective. Use at your own risk.
Actually it's because I realized that I could make three quarters of the money while working less than half the time :) I'll never be rich, but I'll always have time to tinker and do a bit of volunteer work. Also, no commuting, that's a good 10 hours a week I'm gaining for myself right there.
