I was a great admirer of Steve Jobs. He was a business genius. Effectively saved Apple, as well as Disney. He was a difficult person, of that, there is no doubt. He treated people badly, even his first daughter, but also many employees. In part, that led to his business success, but made him feared as much as respected.
His 'flower-power' ideals meant he refused treatment for cancer until too late. He believed diet was everything and lived on a vegetarian and sometimes very restricted vegetarian diet, for years.
