The one stupid purchase every rich person makes

The gist

1. Large houses are a near-universal regret among the wealthy, with most owners using only a small portion of 10,000-plus square feet.
2. Williamson argues someone earning $50,000 a year with a free schedule is effectively wealthier than a billionaire tied to work they dislike.
3. Private jet travel is the one material luxury billionaires like Sam Zel and Scott Galloway say is genuinely worth the money, while yachts are seen as burdens.
4. Of 400 profiled entrepreneurs, only two lived lives worth emulating, suggesting extreme wealth often comes at the cost of health and relationships.
