I met an old friend who we separated for about 4 years because I relocated to a very distant place. We sat and discussed for hours and I discovered that he is a professional gambler. I mean he has nothing else doing apart from gambling and yet he is leaving well and comfortable.
He is only just lucky, but you can think of rich people in the past that later become broke. I am not saying your friend will become broke, but what he is doing is highly risky. If he has won good amount, he should focus on other aspect and getting far less dependent on gambling as he is only lucky.
Let's discuss, does anyone here plan with gambling money yet to be won?
I can never think like that, he can lead to a miserable, uncomfortable and depressing life for most people that think like that. Never depend on gambling, get a good business before having such idea.
I understand your point, but the OP has said that his friend is a professional gambler and not just a rich bloke who doesn't know how to control its money and finds himself gambling without even trying to win or haven't got a good game plan to sustain his financial needs and status.
Professional gambler might not be a good business to start with because yes, gambling is a very unpredictable sport and expensive vice. But we must know that only few people are just called to be living a life like that, it's like they are born to be like that. Professional gambler is a thing now especially if you're focusing on sports where your chances will increase depends on how you will analyze the available data unlike to a casino where it's just mostly luck-based games.
