I have a lot of self-control when it comes o a lot of things, gambling especially. This is probably because of my love for money and I gamble knowing that I will most likely lose what I wager.
The suggestion is either 1. not gamble at all, or 2. set win/loss limits and stick to them. Losing sucks, but losing more sucks even more. You're not supposed to gamble thinking you're going to come out ahead; it's for entertainment purposes only. If you come out winning, GREAT, congrats, but don't expect it again. You and I both know it's only ever about how lucky you are.
I have the same suggestion with him. I just want to add that if you choose option 2 which is setting win/loss limits, you must be self disciplined. Setting limits will be useless if you are not disciplined to stop yourself on playing and go beyond that limits. I'm in control of myself in terms of gambling. I'm not even into putting coins on gambling site and just play with free coins there before. Maybe just a matter of self discipline/self control and financial control.
Yeah this is key, I will also recommend to whoever wants to gamble must setup a special account or wallet and put your daily, weekly or monthly budget there and to only use that money, if you like playing in a real life casino, you must not take with you credit cards, debit cards or anything valuable that way if you lose your money, you will lose only what you were willing to lose.
Playing online requires even more discipline because the games are faster and there’s not a way to physical limit yourself but it can be done.
