If you read my post carefully I have already mentioned that I do take occasional breaks to maintain a healthy gambling.
As you said, bet size plays a crucial role too. In the beginning I used to play with higher amounts but as I kept losing I realized there's no point.
So I started betting with smaller amounts and that helped me in cutting my losses.
That's good. Because you already managed to cut losses by controlling the amount that you'll spend in gambling while still enjoying your time and not pressuring yourself. In my case I don't often gamble due to work but when I have time for leisure (gambling moment), I have a set budget, so win or lose that's the only money I can spend in gambling.
In addition, choosing a game where you're often lucky is a good choice since you can stay longer playing. That's why I prefer baccarat and blackjack live games, it's more entertaining for me.
