I am taking a few moments today to thank Stephen R.
Covey for changing my life. I can date his influence clear back to when I was a teenager and the principles he taught have been used throughout the entire course of my life. Covey was a Utah guy, a professor at my university and a member of the LDS church way before he was the giant man of leadership he is today. Philippeboukobza. Lectures heuristiques.
