Here I shall quote from something my husband once wrote:
If you don’t act with integrity all the time, where does it begin and end? Do you start acting honorably when you leave the house in the morning? On the drive in to work? When you clock in? Only after your second coffee? When talking to your own people? Existing customers? Potential customers? When you preface your words with “Simon says?” If you don’t display good character and integrity at all times, why should I trust that you’ll act uprightly when dealing with me?
Free-write on this topic, or apply to a fictional character–in any way that appeals to you.
