The worst mistake any gambler can ever make is chasing your losses after losing money, learning risk management is very important
Even if there's a possibility that you might recover, the best strategy is to do nothing for a while, give yourself a break, this is where self control comes in.. chasing your losses or using the martingale system might just put you in a more precarious situation
If it's a casino game just do your best not to play again, find other things to do to get your mind off it
Always tell yourself that the money you lost is gone, don't try to get it back, instead learn from your mistakes and move on
Yep, that usually happens when someone gambles with a loan money or money that shouldn't be used for gambling. With good and strict money management, that will not happen.
I always keep myself busy with work or other things after experiencing losses that cost me money that I could use for gambling, that must be done so my minds can focus on other things - Because I might try to find/loan money to gamble again if I only think about the previous loss.
