Think positive, happy thoughts and act as happy as you want to be.My refrigerator is a rotating photo gallery of people I love. Many people spend time in my kitchen and check to see what is new. We started an experiment early in 2010 to see if the statement at the top left corner of the photo are true. Yes they are! The statement in case you can't see it: Positive behavior change comes with making right choices over a period of time until the choices become fixed as habitual or natural. Once they are natural they no longer seem to be subject of choice, but of the natural flow of oneself. Think positive, happy thoughts and act as happy as you want to be. And you will be that happy.
