10 years of gambling yet still not making it, I think he really needs to find another way of making money already and stop focusing on gambling. He already wasted a lot of time on it while also losing a lot of money. He could have bought a car already if he saved all those loses.
Since you seem to be a close friend and have concern of him, its time you get to intervene and say something about what he is doing. A good friend would always lead a friend to a better life.
Sounds unreal but there are people who are really persistent with gambling hoping that they might make profit from it one day...From my experience I discovered that the more you keep chasing losses the more difficult it would be to catch... just because people are winning doesn't mean that it's possible for everyone to win, it's important to take a break when you figure out it's not for you
We can be persistent in our confidence of hitting it one day, but our expectation should not be built base on desperation, because those who think they can only survive by what they come out with from gambling will end up being disappointed, because in gambling, there is more tendencies of losing than winning bets, so we have to be more careful and know what is ahead of us, so we don't end up on a dashed expectation.
