When will you feel 'rich' and what will you do afterwards?

This post is prompted by the previous post I read about somebody with £2-3M net worth + will inherit £7M but still doesn't feel rich.

What do you need to have to feel rich and what kind of changes will you make in your life afterwards?

About 1.5 years ago, I felt rich enough to: - take a 40% paycut to leave big tech and join a startup with a social mission - stop looking at the prices of food in the menu when dining out - I would just order what I wanted - take an Uber whenever I wanted (which turned out to be only twice a month max)

(funnily enough, I'm now a bit bored of feeling content, if that makes sense, and now thinking to join a highly ambitious startup again to feel challenged)

What about you?
