I know someone that gambled for the first time that lost the game immediately and he told me he is no more gambling again.
In my case, when I started betting on sports, I only lost for 2 weeks. In every game I bet on, I lost. My bad luck was so bad that I even lost in games with odds of 1.10. I didn't know how to analyze games. I just bet based on the teams I knew. The funny thing is that after two weeks of losing, I was lucky enough to win and then I stopped playing for a long time. Because I realized that I didn't have enough knowledge to continue with sports betting and I was very tired of losing consecutively for 2 weeks.
