"For the past 33 years, I have looked in the mirror every morning and asked myself: 'If today were the last day of my life, would I want to do what I am about to do today?' And whenever the answer has been 'No' for too many days in a row, I know I need to change something."
Steve Jobs, Apple co-founder.
It is characteristic of Mr. Jobs to have viewed change as something he would initiate.
It's not as simple as that.
More typically we react to a demand for change rather than initiating change, a demand forced upon us by circumstances we often don't control.
Be prepared to do both.
You can start it, others will start it . . . whatever the case, be prepared, it will happen, change is constant.
