I must agree with this. When you think that your losses have obviously outnumbered your winnings and your funds have been affected already, I think the wisest decision is to stay away from gambling temporarily because that’s the only way you can save again and regain what you have lose.
I think regaining the losses should never be a part of your gambling habit. That means you are chasing your losses. So that will not help even if you temporarily stay away from gambling. What is lost is lost. In gambling, you can't show off your ability or skills. It's all about luck. You can't control your luck or make your luck better for winning gambling bets.
For this reason, you should gamble only what you set the budget for and never go above it. Never chase your losses. And play with only what you are left with. Once one bet is lost, that money is gone. Never regret it and never try to find a way to make that money back. But yeah, it is a great idea to compare your wins and losses. That way you can be sure that you are losing more than you are winning. That's the time to take a break.
