Giving into emotions can be dangerous, but successful is very subjective term. I would take it as being successful when we don't lose everything by playing everything we got, or even more then we budgeted. That's a win in my book. I don't necessary wait for huge profits in order to be successful. Just minimized losses. As long i am losing what i am affording to lose, i consider myself a successful gambler. That might be a low bar for someone but it keeps me straight and far from the trouble and deep end. And i consider myself greedy, not so desperately greedy i would play with a loan or anything like that. But i gamble with winnings sometimes, maybe with too greedy attitude, but that what gives me big wins sometimes. But only sometimes.
