Constantly shuffle the tiles on your rack even if you think you're great at rearranging the letters in your mind. Chances are you'll have words appear that you couldn't come up with otherwise.
There are 7x6x5x4x3x2x1 = 5040 (some probability rule for you) possible ways to arrange your seven letters on each rack.
This can also be more useful if you start noticing which particular letter combinations help you see certain words. For example, CK and GH are two letter combinations in many words. There are common three letter combos like NDL and STR.
