Getting Past Level 1 Thinking?

I haven't played poker in awhile and was thinking about getting back into live cash games. The last book I read was Professional No Limit Hold em. Good book that put an emphasis on stack sizes. I plan on re-reading that and taking andre's suggestion to get Harrington's cash game books. Any other ways to get past level 1 thinking?

 El Maquina,

Read this review. :)

I was writing out praise for Phil Gordon's Little Green Book, in response to your question, but then I came across this and it said it better than I could:

Thanks andre, I'll check this book out. Gonna start playing some cash games again and want to do more then just be tight and wait for good cards to come.

Where do you live?
