That's not a fair statement... He has accomplished a lot by most peoples standards. If you're are implying that marital success is worth more in life than career, I wouldn't argue with you but I do disagree that one is objectively more valuable.

It really depends on the individual.

Clearly Elon made his choice, but he has kids he loves and a business empire. I wouldn't even go as far to say that he did it just for the sake of business success. I think he has long ago dedicated his life to the human race as a whole and his success in business came as a byproduct.
