A good friend of mine, Dr. Dan Diamond found this video and I absolutetly love it! Here is how he described it, I could not have said it any better myself:

"No doubt, negativity is contagious and can spread like cancer. But, I believe, an engaged and enthusiastic employee will have much more of an impact. People are searching for significance and purpose.  This video reminds me of being in a totally dark room. Just a small light can have a profound difference. (Be sure and watch the whole video.)"
