Are you confused by the nature of happiness? Or, by the usefulness of positive thinking?
This picture from Roy Goodman explains the essence of happiness.
The idea is to live happily. Period.
Being successful, or getting somewhere, doesn’t make you happy. Nor does being happy get you anywhere. You just chose to be happy, or not, as you are getting somewhere.
