Welcome to FTR.

I play 10NL and find that most of the time when I try to "play the player" its because im on tilt and it actually doesnt have a +EV.

I find that the most you need to do at the lower limits is find out what sort of hands they like to play (e.g. loves suited cards) and what sort of % of hands they play/raise. The other important thing is how much they are willing to call with common hands like flush draws and single pairs and things like that. Im not talking numbers im just talking something vague and general like "lots" or "not much". Then you can milk them pretty easily when you have a hand.
