I have heard that it is impossible to smile and be sad. I can never remember to test the idea when I am sad.
Motivational speakers often emphasize the importance of thinking positive thoughts. I have heard the expression “fake until you make it.” I take this to mean act successful and happy and you will be successful and happy.
When I was in high school, I had a multi-millionaire (owned banks, a ranch, a successful restaurant, and other businesses) tell me that if you laugh the world laughs with you. If you cry, you cry alone. I decided not to argue the point since my father worked for this millionaire.
So today, I am going to use happiness as a tool. I know me pretty well and I know that as the day goes along how I feel may shift as normal moods pass along, but even if I have to lie, I am going to tell everyone that I am happy. I am going to laugh. I am going to smile at everyone I meet. Even if I have to fake it till I make it, this is going to be a make me happy and make other people happy day. I am going to use happiness as my tool.
