If the daily work is built around being in the flow and rhythm then mental muscle is not that much stressed.
You wake up, you know that your limo is waiting in 20 minutes. You'll start with a scheduled call on the way to gym. At the gym personal trainer makes sure you're giving maximum. Then the limo takes you to the private jet so you can catch the conference in Europe at 4pm. etc.
My point is, if the world around you revolves in a rhythm where falling out is not an option, you can find the balanced flow and rhythm so 100+ hour week full of balanced work is absolutely normal. You just stop wasting non-work time over the weekend and use it for maximum recovery and family-time.
Add a bit of humour and laughter to these 100+ hours and stop caring about issues you can't fix and it's a paradise to live in.
If you have the insane financial position that someone like Musk does, it gives you the ability to edit a lot of annoyance/stress out of your life. Most of the day to day crap that most of us deal with can be automated or delegated away.
