I think everyone hit it on the head, keep adding little by little to your game. One thing I personally look for is how many bad beats you are talking. The more the better, you really want to be in as many pots with the best hand as possible. From there, you can determine if you need to change how you play the hand or if you just ran into a cooler. If you are always behind, it's tough to make adjustments other than tightening up.
