I think you're right. Some people always lose in gambling because they don't have plan. just play, play, bet, bet. If they lose, bet twice
so they can take back what they lost and then after that the money will be gone so fast. Because Winning in gambling is instant and of course you be will lose quickly too. I know gambling it's very easy to win or get money but you should know how to control yourself, control your emotions.
Mindset is very important and powerful when it comes to gambling don't be too greedy
and think wisely and carefully. Always set limitation for yourself
This is the usual emotion of most gamblers, being greedy. That's human nature we can't totally avoid.
But such emotion varies from person to person. Some people are good in handling themselves as they stick to their plans.
It is like, win or lose on the next game, they know they need to stop. Those are gamblers who knows when to stop and hold themselves.
Most of the time, those people are not addicted as they can contain themselves from possible addiction. Not many gamblers can do that.
