What is my weakness in poker?

I've been playing online poker a lot. My strategy is to always play it safe and never take risks. I just do not bring and to call if I know I have the best hand based on the cards on the table. For example, I QQ and raise to all. Someone could call my raise and the flop comes AKJ, I Fold the second, he invests. If it was something less than Q 9, such as JT, I bet. This strategy has worked pretty well so far, and it seems foolproof. So what is the weakness of this strategy? I guess people are not bluffing that often, because it is a bit risky. Does this mean, I play really loose?

Sounds like a weakness is too tight. You know what I mean is loose? If you raise the QQ, I'm going to call you with any two cards, knowing I can only raise at any Ace or King hits.
