I've always been one that takes certain principles and values seriously. Things like honesty, morals, ethics, always bring a certain sense of solid dependable character in a person. While we all have weaknesses, and sometimes we make excuses for occasional lapses, those who keep a high standard are continually valued and respected by others.
How we rate ourselves objectively is key. How we tolerate situations of weakness of others is another battle. A few of the latter situations come to mind: a situation where a management individual was determined to find ways to berate and belittle any manager or staff, inside or outside of reporting structure, who was not in alignment with her power seeking needs; a individual who dominated every conversation; a staff individual who was determined to cut every one else's ideas down; another individual who continually showed up late for work, not appear to do any work, and would dependably disappear when the boss was away from the office; one acting manager - lead who would instead of working and growing his team, would rather spend his time socializing with those who he believed were people of corporate influence.
While these situations agitate us, how we respond defines ourselves. About the time of one of these situations I happened to purchase a special framed photographic work which I enjoyed.
