Do you have any personal rules for avoiding losing money when betting on sports?

Do you have any personal rules for avoiding losing money when betting on sports? I'd be especially interested in hearing from those who've been in the game for a while.

Over time, I've developed my own rules, and I use them when placing bets or playing unusual games on my favorite bookmaker platform, 1xBet . Although, I must say that recently, I don't bet more than a certain amount and don't try to win back my losses. This approach has helped me maintain balance. It makes the game more manageable. I advise everyone to bet and play wisely.
