I'd never had a significant win, so my first gambling win felt mediocre. And when I calculated the winnings, I experienced more losses. This strengthened my perspective on gambling, emphasizing that it's not a place to seek profit.
And from what I've seen, a person's first win in gambling greatly influences their perspective on gambling, and this also significantly influences their subsequent gambling. I have a friend whose first win was a huge one, a win he desperately longed for. He continues to spend his money gambling, hoping to win again and experience the same high he experienced before. I've tried to persuade him, but to this day, I've failed.
