Self-control is not something that you just say you have but a skill that you need to develop while playing, your good anticipation
plus, your understanding with the type of game or sports that you'll going to bet in.
Greed is always behind but with good control of emotion chances that you will enjoy the possible benefits of your gambling participation may occur.
It's more on thinking positively and not to be careless when opportunity is already in front of you, choose wisely and enjoy playing.
Self-control must be trained continuously, especially in gambling games so that we can know when to stop gambling. If not, we will only experience difficulties because we cannot stop and will instead spend all our money without being able to win. And even though we can win, it won't stop us from trying to win more and that means our greed has increased and we can no longer control it. And that will obviously make us addicted to gambling, which we cannot control because we just want to gamble for a long time. Playing gambling longer than before means we are taking a greater risk of losing money than before.
It might also depend on who that person is that won big once in a lifetime. If it is someone who knew forever how to deal with money, how to avoid buying unnecessary items and whatever else some could afford, then it might be possible that someone just walks away from gambling.
But there are many examples also of lottery winners who wasted their money in a way that at first seemed to be impossible. That's why I said 99.999% because I doubt that it is the overwhelming minority which would stop gambling forever.
Yes, managing big winnings is not as easy as we imagine because we will definitely be tempted to buy things that we don't actually need but just follow our lifestyle so we won't know how much money we have spent to buy these things with money the win we got. This also requires self-control to be able to deal with the winning money that we get so that we only buy the things we need and save most of the money for our future or use it to create a business and invest so that we can have a source of income.
Many lottery winners waste their money in improper ways, such as buying things they don't need. Only a small percentage can really use their winnings well and prepare their future well too. These are the people who can change their lives for the better in the future. They don't mind if they still live simply with the winning money because they only think about their future with the winning money.
