The bet reminded me that resistance is the key to winning, many games come back at last. Secondly, the bet has helped me find the right people to trust in my social life. Just as some teams are unreliable.
Do you mean gambling?
Well, you can really find many friends in gambling, just like the drunkards find their pals in gambling too most of the time. I believe that those are some of the good effect of gambling to gambler, they could find friends and they feel comfortable with them. But the bad thing about that is they are pulling you more and more into their position. They could also pull you to the wrong direction.
