Other people and things make me happy
Just as money can't make you happy, other people can't make you happy either. No one can make anyone think or feel or do anything. The only person who has that distinction is the person who owns the thoughts, feelings, and behavior. When you accept this truth, then and only then can you be truly happy. If you stop waiting for circumstances to change in your life, you can make yourself happy - every day - no matter what life brings.
