Hi Gang,
There are varying opions on going back and doing a reproof on older posts. Yes do it! No leave it it shows your growth. Since I am in the developing business I choose to leave it as is. I know that I am a different person than a year ago and I have not posted anything except the book review for Leadershift, in over a year I will just leave it.
My biggest change was becoming a Certified John Maxwell Coach, Speaker, and Trainer. I have met so many people and learned so many things. I became aware of myself. That inner awareness bring forth so many things. I can see how much I need to grow and change my inner thoughts.
