Good advice - When You Want to Move On. I think about this concept very often when I'm upset about how someone treated me. I think, 'Let God take care of them because that's his job, not mine.' And you know what, I instantly feel better and then move on!
"Beginning today, treat everyone you meet as if they were going to be dead by midnight. Extend to them all the care, kindness, and understanding you can muster, and do it with no thought of any reward. Your life will never be the same again." - Og Mandino
