If gambling is good for you and you see it as a means of entertainment and not to make money, you should not quit. From what your explained that you almost quitted gambling but because you have won the last game that you staked on, that have motivated you, and now you want to change your mind from quitting. It shows that you are gambling for profit, so I would advise you to quit gambling, if not, you will continue running at loss and you will regret not quitting. Yours is better, you are still thinking of quitting, some gamblers inspite their losses, they don't have quitting in their minds, but how to win big.
