I don't have long gambling sessions that would last for years. I played slots sometimes, sometimes poker. A little roulette. However, I want to say that I have only positive experience of online gambling. I didn't win much, but quite a lot for a beginner.
Maybe that's why they say that beginners are lucky, or maybe it was just a coincidence.
Now I almost don't gamble. In any case, I have only positive emotions from gambling.
