Elon Musk is already a big-time middle-aged man, but he still plays LEGO and Elden Ring. This curiosity about the world and playful mindset is super important—someone asked him what he would do if SpaceX and Tesla disappeared, and he said he'd immediately figure out what to do next. In China, this is called '折腾劲' (the drive to keep hustling), and abroad, it's called JUST DO IT. I suspect this might be genetic. His mom's brilliance only started at 60: walking the runway, publishing books, and more.
