No way I'd like to swap with most of the big CEOs, but I would like to swap with Elon Musk, for the simple reason - the former are businesses, mostly arbitrary to me (and, arguably, to them). In case of Musk, his businesses are all just vehicles to achieve goals (pushing humanity out into space, electrification of transport to combat climate change) - goals that strongly resonate with me. I think Musk can pull off the workload he does only because he cares for those goals, not for business.
