If I ever play and win the lottery this is the one thing I would spent big money on. No expensive cars, no expensive wine, just a person which takes care of everything.
Need a new insurance for the car? Tell the secretary to do it. Car is broken? Tell the secretary to take care of it. Need a hotel? Tell the personal secretary to book one. Phone broken? Just send an email "Please order me a Samsung S8" and it will magically appear the next day. Don't like it? Just tell them to send it back.
This would solve 95% of my daily struggles and it would improve the quality of my life way more than any expensive yacht or car could ever do.
In fact if you have a group of half a dozen people who each pay a few hundred $ a month you could almost employ one person who takes care of such stuff even as a not-so-rich person.
