As an alternative answer I'll iterate from my own personal experience - the worry of money can go away. Your world is limited only by your imagination. I think some big-shot nerd said that once.
Also I wanted to add, I have friends and many acquaintances who are million/multi-millionaires whom I've observed over the course of my life. The culture on that level is discomforting. Poorly-educated homes compared to educational access, excessive partying (drugs or purely social), and a really weird desire to save money? Like a good amount of who I've been exposed to, they LOVE shopping at thrift stores and getting deals, which ironically ties-back to the article here.
Weird!
