Years ago my employer decided to have Dave Grossman come out and present a seminar. It was nothing short of life-changing, and I do not impress easily. It occurred to me that many in here may not have heard of him, so I am just passing the word. Check him out; read his stuff. https://www.facebook.com/profile.php?id=100050451191627

....among fellow assholes. I'm lovin' the site and look forward to the book.
