Nothing endures but change. This phrase, which we have attributed to Heraclitus, was probably around in one form or another since the beginning of time. Each one of us, without exception, changes as we age. Why do we change? Change is a basic survival mechanism. Changes may be viewed as caused by internal or external factors. Youth and inexperience love change. As we get older, we develop a resistance to change - at times to our detriment. Adopting and promoting change in our lives as well as the lives of others is a progressive and entrepreneurial trait.
