I doubt someone whos a losing player for 3 years has any of the traits needed to be a pro. I was a losing player for maybe a week. Maybe i have actually never been a losing player at all. Hard to say with variane
And im not even a pro.
The most important trait you need is wanting to be the ***** best. Every game i played before poker, i was in the top 5%, sometimes the top 1%, in 1 civ3 i was actually the top 10 players. (there arent so many who take civ3 serious, that helps) This mentality i think is universal among poker players. You study poker not primarily because you want to make money, but because you want to be the ***** best.
