There is a statement he made there that "No matter how much you win you can never get satisfied". Yes this is a result of not being able to control himself, like as I always said whenever you have the first winning its just like giving you a free ticket to keep gambling because you would have this mindset that there are other possible huge luck out there you could win higher than what you have won. Of curse there is every possibility that you could win higher or above what you had won before but have you also consider the other side of yourself what it's causing towards your life because to me, when you gamble and win it increases your interest to keep gambling the more at this point you won't know when you might got sink in gambling addictions.
If it is on a winning position then that's clearly greed. Self discipline will indeed aid this however it is the hardest thing to imply to oneself, which makes this a bit understandable. Personally, I am guilty of such thing, there are times I would be desiring to earn more than to settle with a small profit, then end up with a complete loss but that's gambling. It will never be too late to make a change for yourself, for the betterment, all you need is to have the initiative or else, quit gambling because in the long run you'd more likely just be in deep loss.
What exactly do you think we call this type of gambler? For he is not only addicted to gambling, but he seem to be also addicted to buying stuffs he obviously does not need, and absolutely not interested in..
Again, alot of money can be made through gambling if one is lucky, but it also can destroy the person if he or she does not, or fail to control him or herself..
That guy might have a shopping addiction if he spends that much on the things he wants, but I think it's not a bad alternative if he'll be gambling his winning at some point. It reminds me of an old topic mentioning your winnings and spending them before it's too late.
The lucky win probably gave him a lot of confidence and maybe that's why he couldn't resist playing again. I've experienced that same situation, and eventually, you could be giving back your winnings within a short time if you start chasing your losses.
Will be absurd to think that he's addicted already. Would be better to assume that he's just having his "wants" more than his "needs" if it causes him problem already. But I agree with the idea that he might got used of buying anything that crosses his mind because of confidence that he will again win in gambling. However, as we all know, gambling doesn't work that way. You may win sometimes but it won't always be happening, or should I say not too often that it will outnumber the tendency that you'd lose.
