Very few people become rich from gambling, most people become poor because of gambling and even go bankrupt and have a lot of debt. Gambling activities are very exciting, there is an exciting sensation when placing a bet and there is satisfaction when winning a bet. Maybe that feeling is what makes people addicted to gambling
But the funny thing about gambling is that we know that the chances of winning are smaller and the chances of losing are bigger, but we still gamble

Yes correct, very few becomes rich because mostly people who gambles only think straight that they need to gamble and win so that they can be easily to get rich. We should avoid that kind of thinking because it will only make us more addict and also will give us bad result in our finances. We should learn to manage our emotions towards gambling so we cannot go wrong.
So, what will be the right thinking when it comes to gambling if that should be avoided?
For me is, there's nothing wrong with that kind of mindset and I don't think that there's enough reason to avoid it. What people need to do is to make it easy every time they play. Remember that in every emotion you feel, your decision making and your body movement will react. It means that you might make a move that would make you lose like playing in a rush, wrong placing of bets and so on.
