Good Behavior

6. Noisy Eating

You're aware you make sounds while you munch, but aren't sure why. Tape-record yourself to isolate whether you hum, click or make sucking noises with your tongue. Finding the specific sounds helps you focus on the solution, which could include changing where you keep and how you move your tongue during meals, chewing more slowly, chewing smaller pieces or keeping your mouth closed while eating (which is always a good idea in front of company).

7. Being Late

Conquering this habit requires a compelling reason to be on time for appointments, says Ken Lindner, author of Your Killer Emotions. Ask yourself a few questions: Do you respect other people's time? Do you want to appear to be rude? Or would you like to be perceived as thoughtful and professional? When you decide to change, start by visualizing your arrival at an event five to ten minutes early—feels good not to annoy others, right? Or try writing down appointments 15 minutes before the scheduled time to ensure your promptness.
