Emotions are contagious. We've all known it experientially. You know after you have a really fun coffee with a friend, you feel good. When you have a rude clerk in a store, you walk away feeling bad.

Teachers need to be comfortable talking about feelings.

CEOs are hired for their intellect and business expertise - and fired for a lack of emotional intelligence.

A little girl who finds a puzzle frustrating might ask her busy mother (or teacher) for help. The child gets one message if her mother expresses clear pleasure at the request and quite another if mommy responds with a curt 'Don't bother me - I've got important work to do.'
