First rule of responsible gambling, learn to walk away from the table.
If you start loosing too much, walk away. Don't try to catch falling daggers.
If you made a good win, walk away. Chances are you're gonna lose it on the next bet
I know a small number of people like that, but they do exist.
Greed usually takes over after a bigger win, and in the end, you lose even what you had earned.Responsible gambling is the key, but i know it's really hard.I know from my own experiences, but somehow i always manage to control myself in the end.
