Losing and winning or losing in gambling that makes you lose some money, basically it doesn't matter if your intention is to have fun.
Having a mindset of gaming for fun is actually one of the best ways to go about it but then, when it turns to be about winning, there your gojbg going have a hard time gambling becuase, your mind would be so set on not just winning but recovering all your losses and as such, you see yourself making huge stakes and unexamined odds and bets. You've got to accept that loosing is inevitable in gambling else, you would loose more than you've ever hoped to @BIN-BIN.
The OP says his gambling is just for fun, but he doesn't accept defeat until he asks for help on how to win, and in my view that is dishonest.
Honestly, when I gamble for fun with friends, even the winnings I get I use to party with them which means, I don't expect those wins. But something said in the OP by @BIN-BIN, I think the first thing to realize is to be honest with yourself, what is the purpose of gambling, because gambling with the aim of having fun and for profit, of course has a different way of gambling.
