True but I was also playing 2/4, in january, which is only 10 and 20 times lower than the games I play now. I think anyone can move up to these limits in that time period if they are good without running hot.
I have played online nearly daily for over 4 years. Your history is very far from unique. There are so many guys moving up quickly and after 6 month finds themselves in the toughest games there are on internet. And do good in these games.
All these guys are sure it is their pokerskills that have taken them there. And most of the time it is. But what they dont understand (yet) is that there are so many other factors that becomes important. Like: How do I react when I hit my first really nasty downswing? How often do I play worse then I could? What happens when other good players at this limit get a read on me? Will I not get bored and start to play worse when I get used to the limit I play at? Will I not start to play worse when I become bored of playing poker (like u will sooner or later, maybe not each day... but after a while it is a work, not a hobby)... and so on and so on...
They guys winning big playing internet poker week after week after month after month after year after year got so many skills besides being good at playing poker. And after playing a lot on the net for 6 months and moving up all the time, u dont know if u got these skills. Come back after u have played poker for a living for 12 more months and u will see your own sucess in a different light.
