Each of us has had the occasion to have a bad day turned around by people providing positive support. We have also, unfortunately, had good days ruined by others who rain on our parade. Fact is, most of us do not have charisma that can change the mood of the room. Instead, we conform to the environment in which we find ourselves. While we may not be able to change the mood of the room, we can change rooms. Start each day with a positive affirmation. Begin each conversation with a smile and a kind word.
