I think his "special forces" analogy is quite good. Sure, most people won't join the military. Sure, out of those that do, most won't be joining the special forces. Sure, those that do join the special forces know it's "above and beyond", an added level of stress and quite difficult to do for 40+ years, but they do it anyways. Why? Probably because they're compelled by the greater mission and they're willing to do it in spite of the tradeoffs. Oh, and they're the best of the best, so they're probably okay with trading some rest for the work they're putting in. Yes, most people won't hold up under those conditions, but special forces recruiters aren't looking for "most people". I suspect Musk isn't either.
