The whole point of optimism is to look at the glass half full, or look on the sunny side of things. That means going through each day finding and appreciating the good all around you. This means positive thinking, gratitude and joy is embedded in every word and action throughout your day.
So I challenge you to really become aware of what you are thinking and doing each day. Smile at each person you come in contact with. Compliment those around you. Pause and take a moment to look at all the beauty around you. Ask the universe for your day sunny side up!
