Making some profit is hard in the long run, but even if you want to get something from gambling, the first thing you must do is to have a proper bankroll management. I saw a lot of people lose all of their money because of sudden impulse to go all in, never do that if you want to make gambling profitable.
Impulse or not you would still end up on losing money but somehow if you do have a good bankroll management you would able to sustain for longer times compared on to those people who do go all in usually when they play gambling.Pushing this thing to be profitable is the hardest part knowing that gambling isnt really designed for profit making but rather just for pure entertainment.
