Positive thoughts are great and even better when they show up unexpectedly.  My friend told me about a movement to put post-it notes up with positive messages on them and we have started doing the same at work, incognito. It’s only been a couple of days but I have heard several people mention them and they all were just a little bit delighted to have found them. If such a simple thing can brighten a person’s day, just think of the wonders you could achieve if you really reached out to people to help them get through whatever issues they might be having.
