I do think that gamblers who take gambling activities seriously have their motivation come from the amount they envision and hope to win, hence why they remain persistent in gambling instead of quitting after winning a little.
A gambler with a winning amount in mind, gambles much more and can become easily addicted than a gambler just gambling for fun and without a particular winning amount in mind
The issue is not about having target, is keeping to that target. Most people before going into gambling in their gamble section they usually have this fixed amount they can win and amount they would love to win in that section. But most when they are lucky and they endup winning greed always comes in , and they will endup losing more than that target or they may lose that they have won during that section, all because of greed that's why self-control is one of the vital attribute one need have when it comes to gambling.
Exactly, having a target is the start and keeping to the target is the main purpose, in other words we need to have discipline.
That's the hardest thing to do when we are lucky, because the greed is usually stronger than our own plan and discipline but at least we should try the best.
This is why it is important to withdraw when we achieve our target, at least withdraw the amount as we set for the target and we can continue with the rest if we want but it is always better to withdraw all and take a rest for a while.
