First, it is expected to settle one fact before we set out to start gambling and that is to know when to turn down the urge to pull out losses when it happens, some people don't have the balls to stand upto losses, and when it happens its result can be devastating on their emotional and mental health.
So I make sure I have a well planned out activity that will be a distraction abd fun seeking for me incase my bet goes wrong and i lose also I make sure I only bet with the amount I can let go if the loss happens.
