When your mindset about gambling is just for entertainment, you can’t really expect to win.. just my observation. Because when I’m not serious about it, like when I treat it lightly especially in sports betting, I don’t study the games before placing bets. I usually end up losing more. I don’t lose big, but if you look at the record, it’s not profitable or even close to break-even.
But when I start believing that I can actually be profitable, that’s when I do the work. I study the games before betting, and that’s when I start getting better results.
I think that we should make a distinction between traditional casino games and sports betting.
Traditional casino games can be really fun, if you don't have any expectations of winning big. The "entertainment mindset" is definitely better than the "hustling/grinding mindset". Having a hustle mindset can definitely lead you to chasing loses and getting addicted.
Sports betting is a bit different. Personally, I hate analyzing games and conducting research, before placing bets. This takes away the fun and entertainment part. I know that proper research could lead to better results, but I'm just not that consistent and I don't care that much about the "success rate".
