I make a (very humble) living working from home writing and doing research on the internet, but it probably pays about 40-80% less than you're making now. I live a life of monastic simplicity (except for the celibacy thing, which isn't me at all).
I don't do this because it's easier, it's because I no longer have the emotional, intellectual or physical wherewithal to work a high-volume, high-pressure shark-tank commission sales environment anymore: been there, done that for 25 years. When I stopped, it was like a weight had been lifted off my shoulders.
But I had to give up driving, for instance, and learned to eat on a monthly food budget that eliminates almost all meat (about $75 per month). It's a whole other way of living (and takes a lot of adjustment), but it's possible to live within very diminished means if you either need it or want it badly enough. It helps that I was never very materialistic to begin with, and that I never placed my value as a person on what I earned, even when it was good money.
For me, it was a health thing. But it involved letting go of a lot of ego-driven "needs" and a total reassessment of my priorities. Almost four years later, I've adjusted quite well.
