I think of Charlie Munger's "good investment is knowing when it's wise to not diversify". The luckiest people I know tend to have a soft, scattered approach as advocated in the article, followed by striking hard and quadrupling down when they find something that works. Arnold Schwarzenegger is very lucky and he uses that strategy. "My genetics and frame are perfect for body building? Guess I'll quadruple down on it."
He's said that he had a difficult relationship with his father, who sounds like a mean, small-minded man. The posters of half naked men on Arnold's wall probably didn't help.
Bodybuilding was once mocked. Maybe it needed someone who grew up defying norms to make it popular.
