I agree with you. In fact, no gambler should bet aggressively on a regular basis hoping that luck will come or that an opportunity will come. Gambling is all about luck. It is completely unpredictable when positive things will happen.
You're right, for me things have to be this way. In fact, something that has nothing to do with gambling, at least not with slot machines, but with sports betting, I have a friend who bet a lot of money on Barcelona today and they lost. He made the bet out of spite and stubbornness. I told him to be careful with Atlético, and he laughed at me because they say they've already won the league. I told him, "Okay, maybe, there are still results to come, but we won the Champions League," and he laughed even more. I'm not laughing at him today because my team plays tomorrow and I hope they advance, but betting with your emotions, even in sports betting, is sometimes deadly.
