I know this is a pretty general topic, but how do you guys get better and grow as a player? Is it by just playing more hands, reading books, coming to the forums, etc etc?

I think I've had a good start. I started with 1 tabling $5NL and i'm currently playing 12 tables of 25NL on ps. ( Withdrew some money when I tried to work off the ps bonus ). This was last year.

This year, Jan is almost over and I don't feel like I've improved at all as a player, maybe even gotten a bit worse. My BR is definitely stuck, i have some 3-5 buyin swing days, depending on if i run good or bad, but most of the time, i'm around even, up or down a couple dollars over a session. (Usually average 1500 hands a session). My winrate is at around 0.5BB without the bonus, which I think is terrible.
I know it's still a small sample size of around 15k hands but the feeling of no growth definitely gotta stop. Right now, the only way that I'm "improving" is by just playing more hands and reviewing the sessions afterwards. I'm thinking of finishing some books, review and clean up my notes, etc etc. But is there anything else that I should do?

Any helpful input and suggestions would be great.

Thank you
