“Don’t worry be happy”.  You have the power to be happy.  It is a blessing available to each of us, but to create more joy in our lives, we must first become the master of our thoughts, because emotion always follows thought.  At any given moment our emotions reveal how we are interpreting what happens in our lives.  When we choose to dwell on what upsets us, we fuel disempowering feelings and that creates the emotional experience that determines how we react to our circumstances.  The reverse is also true:  Concentrating on the positive not only lifts our mood but can affect our bodies in a joyful, life-enhancing way.  Cheers to joy & happiness.
