Photography a lazy man’s profession?

I was reading a book about Elliot Erwitt, an American photographer well known for his black & white shots of ironic and absurd situations in everyday settings. He mentioned something very interesting that I never really thought of…

“Photography is a lazy man’s profession. You don’t have to train, like a musician or a doctor or a ballet dancer. You only need the modest ability to achieve order and composition, or find the right balance of mood”

How true.
