"Whisper a white lie when no one's listening."
This one is actually kind of fun if you continue to do it all day. Whenever you are alone, lie to yourself. Tell yourself you're Batman in the shower. Whisper your dreams as facts over your morning coffee. You can be the president between stop lights, an astronaut in the bathroom and even win the lottery while taking out the trash.
If you keep telling yourself these little lies throughout the day, see if one of them becomes a fact.
