I want to say that after 4 years of playing poker seriously that it was well worth it. Its funny how my playing style had developed.
It went in order from:
1)Loose Passive (2008) LOST
2)Loose Aggressive (2008) LOST
3)Tight Passive (2009) WON
4)Tight Aggressive (2009-2011) WON
5)Loose Aggressive (2012) LOST, Then WON ALOT!
I feel very comfortable sitting on any Live 200NL. The players are very different from online players not in terms of skill, but playing style.
The last 7 days of playing HU in 25nl, 50nl, 100nl, 200nl. I won $1000 from 2451 of HU hands. The reason why I'm grateful is because I used to lose a lot. I almost never won the weekly tournaments in my college poker club for two years and theres only 10 guys in the club. I spent most of my college stipend money on poker books and playing poker, and still continually get beaten at my buddy's weekly cash games consistently.
I was so dedicated to be good at this game that I played everyday and sometimes I skipped some of my college classes to play. Every time I played live poker, I get a paper and pencil and jot notes down.
For online poker, I played every single type of online texas holdem they had: Tournaments, Turbo-donk-tournaments, SNG, HU, 6-mx, FR, Rebuy. I always wrote notes on the players. I reviewed every single session and how could have I played better. My dream was to become a professional.
All that hard work is paying off big. Went to Vegas and won $1000. Went to California Casinos three times and won twice, and lost. However, it totaled up to $2500. Went back home and played family and friends and won $1500. This is all within 2011-2012.
The buddies that used to beat me all the time now ask me for poker adivce. My friends now try to grab a seat at my left to get position on me.
Hopefully, I inspired others to keep continue the rough times, and trust on the process. You don't automatically become good overnight. Poker is a tough game, you just have to ride the variance.
