I learned from that video that being rich doesn't make you smarter.
if 40% of people owning 5+ M $ do not consider themselves rich, they are pretty damn unreflective.
Personally, I have been a lot more relaxed and happier since I read up on statistics and managed to save a sizeable amount - just knowing that minor catastrophes won't immediately ruin me, and that I'm not doing all horrible in the grand scheme of things. Even though my neighbours may have more money, and Mark Zuckerberg is a few years younger than me - and I have a lot less than he does.
But it took a while of not going on holiday and all my furniture is handed down from people. My clothes have holes in them. But the safety cushion I've saved, which makes me more relaxed and happier, is worth it.
