For a long period of time when I was starting out, I didn't think it could be done. (That's having a positive stream of income from blackjack.) When you learn all the things that are needed for that to happen and they fall into place, it can be done except for one little problem. The casinos are NOT going to let you take money from them consistently. If they do, then either they don't know you, or they are being nice to you, or are grossly indifferent or really incompetent.
