It's all very important, especially the loss limit, because if you don't apply a loss limit then you will definitely stop when all your money is gone, greed and the inability to accept defeat are indeed the perfect combination to make gamblers always end up losing even though they have initially managed to win, my advice to you is to try to be firm in the plan you have made because that is the only way.
Some people have a loss limit, and the loss limit is only set on their deposit. If they exhaust their deposit, they are done for the day, and it doesn't apply to when they win a game and want to increase the amount which they have won, and once they start losing, they don't care about their losing limit; they are always more focused on either trying to recover or trying to increase the balance. If that loss limit could also be applied to both the won amount, it will save some gamblers a lot.
