Funny you should mention meditation. It is something I am trying to incorporate into my life since early this year. Nothing fancy, I just use some guided meditation I find (usually 10 min long) and close my office door and listen to it. Unfortunately, I have yet to experience the full benefit of meditation since I only manage 2 sessions a week. However, when I it properly (ie, I don't get interrupted), I breathe better, my body is relaxed, and the head is clear.
