Cheerfulness is possible when you have a sense of mastery, health, and security. In exhibiting cheer, you radiate good will, hope, health, and happiness. Others see your bright, shining enthusiasm, energy, and optimism; your upbeat, happy anticipation; your joy in living; your spontaneity and genuineness.
A simple, genuine smile will elevate someone’s mood and make his or her day. It’s contagious—radiate cheer, and benefit humanity.
