A friend of mine is doing a paper on Mindfullness. Its a newer technique. You may want to look into it. I know that there are videos which show you how to begin this meditation online.
I was taught to close my eyes and do some deep breathing. Then I imagine a small red ball in the center of my mind. Every intruding thought moves the ball. I then use my "mind power" to simply move it back to the center. After ten minutes I am relaxed and refreshed.
