Passivity

My poker understanding seems to be improving all the time, and I was just thinking about the stigma surrounding passive play. Its a fact in NLHE that the majority of the time the EV of betting or raising is better than that of checking or calling due to the effect of folding equity. But this does not mean that calling is a bad play. I played two games tonight where my overall aggression frequency was less than a third. I was playing like a total calling station. During the match I knew that I was playing like it but since villain was bluffing alot and also not giving me much value when I raised, it was the most exploitive way to play. One mistake I think low stakes players make is that they read somewhere that you HAVE to be aggressive; you HAVE to be loose/tight; you HAVE to play style A or style B. This is a fallacy. The only time you have to play one way is if youre opponent plays optimally and you must also play optimally to maximise expectation. Exploit!!. Calling stations dont actually do that terribly typically in holdem games. This is because theyre not making the bigger error of folding too much. They usually lose money by not knowing how to get the best value from their made hands. Their money comes from opponents who dont cut out their bluffs. The reason the lags have made so much money for so long is because players fold too much.
What Im trying to get at is this:
Do not play one dimensionally.
