Everyone was jealous of the next level up. I was making 300k and my high school hometown friends were like "holy cow, you're so lucky this is amazing, you have your own apartment" meanwhile I was annoyed I couldn't keep up financially with my trust fund boyfriend who had $3 million a year to piss away with random trips to Bermuda. My CFO was jealous of the Principal who could take netjets and didn't have to fly first class everywhere. The NetJets guy was jealous of the billionaire principal who had his own jet. That billionaire was jealous of the main money dude who had family money inherited from the crusades. They all fought with their wives over private school tuition and horses. Everyone drank, did tons of drugs, had dramatic affairs and fought like cats and dogs with their families.
I left finance and went into healthcare and realized I'm pretty damn happy living a simple life. I kept a $1500 belt I bought from Henry Bendels that's incredibly ugly as a reminder of dumb decisions and having too much money to piss away on stupid crap!
Read Blood Diamonds: Tracing the Deadly Path of the World's Most Precious Stones Book by Greg Campbell. Reading that made me realize how our planet has finite resources and I just I wanted to cleave the my own consumption habits so stopped needless shopping for "fun" and started being a stubborn bastard about driving my 12 year old Hyundai into the ground. It's not much but it's my own private rebellion against the gaping maw of endless consumerism.
Worship your family, friends, love ones, health, music, doing things that make you feel alive, shared experiences and nature over shiny toys and stuff that just sits around collecting dust and looking pretty.
At the end of the day, we're all the same food for worms anyways no matter our net worth. Enjoy your friendships, realize they probably have their own internal struggles and problems they're dealing with and try to be there for them in whatever way you can!
