How long is a piece of string?
It is impossible to say how much money you can earn from Poker, even as a recreational player it all depends on how much time, money, and hard work you put into it.
You will never make any money if you are not willing to study the game, and practice playing, then study more,
Many people think it is "Money for Nothing" playing Poker, but it is a hard game to master, Doyle Brunson often says it takes 5 minutes to learn and a lifetime to master, and no truer words were ever said about the game.
I have been playing for over 20 years and still will never play in a World Poker Tournament, not because I cannot afford it, but the Idea of playing for 5 or 6 days, just does not appeal to me. I like to enter a game knowing it will all be over within a single day.
I never play more than one game at a time, not because I fear playing multi-tables, far from it! I did that years ago and found it hard work to concentrate on more than one game at a time.
Poker is a hobby for me, a little bit of fun that I enjoy, some people will go to a Football match or Baseball game, I would rather watch paint dry, it's less boring! You have to find things that appeal to you personally, for me it is Poker! because I can take part, and be part of it. Watching someone else having fun is not my thing.
When the fun Stops, STOP!
