• The larger the crowd, the larger and slower the gestures.
• If you have a small crowd, or if you are videoconferencing, or on television, use smaller gestures.
• Work to eliminate distracting or nervous gestures, but do not kill yourself to add new ones. They will take care of themselves and most of the time they look affected.
• Let your words trigger your actions. If you are counting, hold out your fingers. If you say no, shake your head no.
• Hold your hands open and wide apart to show sincerity and honesty.
• Hold your hands behind your back during question-and-answer sessions (don't overdo it).
• Avoid excessive hands in pockets, clenched fists, pointing, hands on hips, and the infamous fig leaf position where your hands are crossed in front of your groin.
