Knowing when to drop. Articles anybody?

[AcidJazz]

I'm rather new to all of this and so I've been playing pretty low limit games online. I'm studying and reading books as much as possible (it's been about 2-3 weeks now). I feel I'm pretty good at knowing what to play at first (how much variety is there really). I fold quite frequently (the two books I've gone through most of are Holdem Poker for Advanced Players and Winning Low Limit Holdem). Anyhoo if I hit something on the flop (typically high pair with a big kicker or two pair or it gets even uglier when I flop a set and I get beaten.

Quite frankly I'm usually pretty confident when I win and when I lose I have this doubt within me. I know it sounds as if I'm answering my own question, but I don't want to get outbluffed all of the time. Should I play conservatively until I begin noticing that I'm getting bluffed frequently? I never get bluffed so I figure this is the way to go.

If you have some articles out there that specifically talk about this, I'd be appreciative for the help.
