get back to gambling only if you have a strong control over yourself
Sure, you need a great self control in order to become a good gambler and that doesn't comer easy because many have fallen short of this virtue and have often lost under painful circumstances and so it's laudable if you learn self control before you gamble again.
this might be the biggest capital of gamblers.
learning to control oneself becomes the most valuable capital in gambling.
I am almost the same as you learn to control yourself before going down in gambling
Gambling can boost your confidence like you say but try not to get overconfident as that can plunge you into addiction and will make you loose a lot of money. Self control also comes in when a gambler faces a series of losses but it hurts to learn it the hard way through gambling though.
