Our day is full of many small choices, choices which hardly take our time. I have realized that it is these small choices that decide the quality of my day.
For example, I have a tendency to pack some of my days with appointments. I am an introvert. If there is a typical advice for any introvert it is not to overwhelm himself. This choice of scheduling things so as not to overwhelm self is exercised in the matter of a second. It is exercised when I choose not to yield to an appointment or two even in the face of many demands on my time. This small choice that I make on a daily basis retains or destroys my otherwise high quality day.
