I watched a rather regular guy launch a non-tech company in the middle of a divorce with primary custody of two very young kids. That company hit 5 million a year in just a few years after launching. Seriously. He just thought his current employer sucked and that he could do better, and he did.
Have I done anything like that? No. But my iPhone apps are making me enough money that it's like having an extra part time job. I started in August, with only a maximum of about 2 hours a night to work on them.
You need to think small. Really small. You need to actually finish those projects.
