As a leader, you are bound to have bad days. They are unavoidable.  And unpleasant. It is tempting to share the pain. But when you are having a bad day, don’t ruin everyone else’s just because you can. 

Don’t leave kind words unsaid.  And think about whether harsh comments are necessary even if they are true.

If you must take it out on someone, go home, smack the dog on the nose with a newspaper, and yell at your spouse.  With any luck, the dog will bite you and your spouse will make you sleep in the garage. That will help put things in perspective.
