I tried several times to play patiently,setting a daily,weekly and monthly bankroll and tried to stick to them if I lost (but not if I won) and that destroyed me.When I was winning the euphoria got the best out of me and I started increasing the bet or playing not so concentrated at what I was doing and soon enough I saw the bankroll at zero.
I am still trying different ways on how to have greater self control when winning but yet I am not able to do so.
That's the thing with gambling, even in a highly skilled game like poker. You can be the best player in the world, knowing all the odds and the correct pot odds bet for every scenario, but unless you have the patience then it can all be for nothing. It really does become like a job and one that you have to grind at every day, which can strip the whole element of fun or entertainment from it. At that point they're not even gambling any more, but making business like decisions and working with the correct bankroll is critical as well. Outside of skill based games you are literally burning your money in the long term, because they know that even a tantalizing win will just be spent on more gambling and the definitely profile players in this way.
