Back on a gruelling field assignment, I was attempting to read some new agey self-identification book a friend recommended. At the point where it got heavily into spirituality, I put the book down. I didn't need that horseshit when I had an 0330 to 2230 assignment in the oilfields of the Pe4mian Basin, 7 days a week... including getting shot at.
BTW... on the subject of "mindfulness", here's the best book review, EVER (Amazon has since taken it down):

Enjoy.
