My nephew is such an inspiration! He has lost over 100 pounds in about 16 months......he logs his trials on fb, he wrote this a couple of weeks ago:
Significant change doesn't happen overnight. It takes a vast amount of patience and effort. There are no true shortcuts to any lasting progress and achievement, for there shall be an even easier path to regress. The greatest efforts and sacrifices that you put in are the most rewarding, because it is then that you realize how much that change really means to you and what you were willing to do to achieve it.
I have this tacked on the wall of my cubicle at work so I can read it every day. Hope that it helps someone else too.
