Every day, when you enter your office or meeting room, mentally wish everyone happiness. This simple act of kindness will make you feel good. Your happiness will then unconsciously be reflected in your attitude, your facial expressions, your posture, your tone of voice... all these good vibes will be picked up by people and they will like you, and want to help you succeed.
