OP, about a year back I met man who was day trading (or learning to trade) full-time. He also worked 8-10 hours on each Saturday/Sunday, teaching English to Chinese kids via internet. He didn't speak any Mandarin so I guess it was some sort of conversate deal. He claimed he was able to meet all of his financial obligations through the weekend job, while he made his go at trading. I don't know the details of his arrangement, but the point I'm getting at is, plenty of low-stress, part-time gigs you could pick up. As an Engineer/consultant, some of them might feel beneath you, but do everything you can to give yourself a chance to succeed.
