Learn some texas hold'em.. my expected $ hourly is more than most of my friends earn at casual jobs like McD's. It's exponential too, because as you move up stakes the more money you can potentially earn. Plus you can play from home and it will actually teach you far more about mathematics and your mental capacity than working a shitty fast food job.
Being an alcoholic and someone that has read up a little bit about counting cards I was once pissed enough that I convinced myself I could do and was doing it, left the crown casino thinking I'd killed it. Got up the next morning and had $220 cash in my wallett and naturally assumed I'd killed it. Checked my bank account and I'd withdrawn $600, was very shady on the night before, so maybe I'd won my last 5-6 hands or something and lost a shit load before hand, was fucking spewing.
