I found this as a status update from Andy Andrews of Facebook:
Do more than is required of you. Aim higher than the others. Laugh a bit more than the joke deserved. Be kind and patient when you don't want to be. Try harder than you did yesterday. Become a noticer and be grateful for the things that you have overlooked for too long.
Wow! Talk about a challenge. We can all use the reminder...and I am so glad that I saw this today.
