I became a larger than life figure for one reason only. When you're quoted in the 'Wall Street Journal ' the 'New York Times ' constantly as the expert in the business people assume you're a lot bigger than you are. And then I had to run like hell to catch up with my own image.
I learned easily and had time to follow my inclination for sports (light athletics and skiing) and chemistry which I taught myself by reading all textbooks I could get.
