Mike got most of it. I would like to say this.

I can only assume you are playing low limits. Playing tight passive has no future. If you try to move up in limits, the fish count will go down and other players will peg you as tight passive in 2 orbits. You will get no action on your bets unless you change gears (which sounds like you wont)
So if you're ok with just waiting around to make a great hand and have a fish pay you off, that's fine. But if you want to play up in limits you're going to need to get a sense or an instinct as to what to do in boarderline situations. You won't be able to get accurate reads if you never bet unless you have the nuts (in which case you don't need a read). Poker is a game of betting more than it is a game of cards.
