Which strategy do you employ most in poker?

We can all definitely agree that poker is more like a game and if you can play it very well, you are mostly going to find yourself on the winning end. Which kind of strategy do you all usually apply to play and how much success will have you been with it. Anytime I am playing, I usually try to be more defensive and I have observed that I usually become successful with it.
