This quote (at least for me) is much easier said than done. Who never looks back? Who never re-tells a story? It IS best to not dwell on our past, but it is a HUGE part of who we are and trying to ignore it doesn't make it go away.
"Commitment. This is my favorite word because in some way, people who are committed are always much more interesting and much more reliable, and much more, I would say, deep than people who are not." -Carlos Ghosn
