I imagine that Elon Musk might have been in a similar position in the past, maybe more than once.
Being like Musk is not the norm. In fact, he has publicly admitted in an interview he did with Bill Gates about China, that combining two CEO roles makes for a terrible work-life balance -- he wouldn't wish it on anyone.
