If you’re playing with money that you can’t afford to lose, then the mistake will be very costly, potentially dramatic, or even catastrophic.
We are all prone to mistakes because this is a game of chance; there’s no guarantee that what you want to happen will happen. The most important thing is that you are accepting your mistakes.
You learned from your mistake and only play with money that you can afford to lose, so even if you made a mistake, you can take it easily and move forward.
