~What about tournaments? There's a buy-in which you have to pay whether you want it or not. I agree with you regarding cash games though.
Yes, tournaments mostly brings more money, and you can choose your level with choosing buy-in size. But the same time leveling-up profit level, your opponents skills growing up too. Not always, but mostly.With this I disagree because there are tens of millions people in the world playing poker online, and most of them do not develop new strategies, or learn them from the contemporary best poker players. It's not that they are lazy or something, they just don't have time for that, having other more important things to do. And you can always find such people in online tournaments, and outplay them. At least that's my theory. "Don't Try This at Home!", as they say.
Those who really put effort to develop their skills will likely succeed as a poker player, however, you gotta risk something in doing that as focus requires time and effort and you might have to sacrifice other things just to be focus in poker games, and the worst part is if you lose in the end as although you are so focus, it doesn't automatically mean you'll succeed.
