Know when to not gamble is just like knowing when to gamble. Taking a break or knowing when to stop is the most important habit I do when I'm gambling. When I loss, I stop. When I win, I stop. When I reached the limit of my set budget, I stop. As much as possible I always avoid chasing losses. I do not let my emotions take away my decisions. That's why it's important to recognize what you are feeling on that day and also check your finances.
