This brings us to an interesting question if hard work in gambling really pays off? If one puts in a lot of efforts to understand a game involved in gambling, does it mean that all his time has gone down the drain? Certainly no. If gambling were simply a blind guess or a wild shot then even years of studying it makes it useless because one is simply guessing the outcome blindly. But such is not the scenario with gambling in reality. What makes hard work count in gambling?
This further sets off the question of addiction in gambling. Work can also be an addiction for many. But here the addiction could be for perfecting the game and the art of playing. This kind of addiction is to struggle every time for success by proper calculation and review. However, addiction can also be due to pure greed of winning with no clear knowledge of the game. If hard work counts, then we may actually find a solution for a healthier addiction towards success in gambling.
I think this can be applied to poker and to poker only. That's a known fact that there are professional poker players who win more than others on average. Although many gamblers think that sports betting is also skill based I disagree with them. I've never heard of a professional sports better who can really prove that he/she is having constant income from sports betting. I think that it's impossible even theoretically because knowing which team will win puts you in a position when you have to risk ten times more of the money than you can potentially win.
I'm not saying you will become an expert after watching those videos, but you will definitely improve your performance at the table. What I've learned is that if you have a really good hand you shouldn't think another player has a better one if he/she is rising big time. You just should think to yourself "What will be will be" and call. Yes, you have a chance to lose, but if your chances to win are much higher, you have to call. Works for me most of the time.
