Positive thinking <> mental masturbation

The author of the article obviously confused between positive thinking and mental masturbation. Dreaming about desired future and doing nothing to materialize your dream is what I call mental masturbation, on the other hand, when you are in doubt, when you are facing adversity in life, when you are experiencing setback in your effort, you don't let them destroy you and instead believe that you can overcome those obstacles, that's what I call positive thinking. This article is definitely misleading in my opinion, but it's interesting to read anyways.
