Those who have succeeded at anything and don't mention luck are kidding...
If they asked me I did two shifts. I did sports I did news because I loved...
I remind myself every morning: Nothing I say this day will teach me anything....
While writing my first 90 books I was magazine editor publisher book publisher executive etc. so I was established in publishing. three of my seven or so books were biographies of sports stars and really opened doors for me in that area.
