Before you give a colleague a piece of your mind, be sure you can spare it.
Being a good communicator means people find out what is really wrong with you.
Believing is seeing.

Beware of a dark-haired man with a loud tie.
Beware of a tall dark man with a spoon up his nose.
Beware of altruism. It is based on self-deception, the root of all evil.

Beware of those wearing suspenders with belts.
