We all of us have a reputation, something we are known for, and sometimes it may be different from what we would like to be known for.

It's instructive to consider the more spectacular and well-known falls from grace of leaders in the public eye... In the main, the issues behind these falls could be grouped under a lack of competence, a lack of support or loyalty from those they sought to lead, and a lack of failure of integrity. Of all these the last is the most egregious, the most fatal. We so much want our leaders to be unfailingly decent that an obvious or perceived flaw in integrity can be the toxin which kills them off.
