That's really what you should do. If you've already lost a lot, don't chase your losses. Instead, stop for a while and just come back another day.
Maybe on that day, you'll be lucky in your gambling.
Let's not be like others who chase their losses, which is a bad habit. We know that in gambling, we usually lose,
but there are also days when luck will be on our side.
It's good advice that is a good start too but between knowing what is good to do, what are bad to avoid, and how you actually do it practically are very differently. It's very hard to follow your initial strategy, plan and maintain your discipline in a long time and in practice. It's harder to control your emotion, psychology and action in reality especially with actions that are related to money, win, loss like gambling.
It's hard to do this responsibly but it's too important for betting responsibly and avoid losing action controls in gambling. Lose or win, if you can not control your action, you will have very big troubles later.
