i got good through hours and hours and hours of playing and reading hand histories ( my own and other people's), studying the game is truly the only way to become the best.
tbh im not really a numbers guy so i dont know my stats, i use no software,
Poker Pwnage is obv the only site i use :)....and the only poker book ive read is "play poker like the pros" by hellmuth, that was a long time ago though and it really didn't help tournament strategy which is my specialty.
