How many games before you know if you're a good or bad player?

[Denman]

I do enjoy a game of poker but it isn't something I'd spend hours playing just to end up losing money. What I want to know is how many SNGs (what I currently play) would I have to play before I can get a good indication of whethe I'm going to be profitable in the long-term or not. Also is it a good idea to ply various different types of poker i.e. Cash, SNGs, Double-ups and Tournaments or simply stick to one game. My prefered style is tight-aggressive but sometimes I feel the blinds go up too quickly and it becomes a "crapshoot" at the end. Any advice would be greatly appreciated. By the way I'm not a complete newbie to Poker I've played for a very years but never seriously really.

Re: How many games before you know if you good or bad? 1000 SnG's would be the VERY VERY minimum to start to give you an idea. 5000 It's starting to get there :) 10,000 How is your average profit looking?
