We were nowhere near as poor as some people, and it was only for a few years, and it was self-inflicted to some extent because I was starting a startup while my wife was getting reeducated. So I don't know what it's like to be really poor. Those stories on HN from people who, 20 years past lifting themselves out of poverty, still hold on to every old sock, that's not me.
But at the same time, having been somewhat poor: damn it rocks to be rich! We became rich overnight a few years ago when my wife got a job, and every time I buy a sandwich without worrying about the cost, I get excited mentally. There's always this "Omg can we afford th- oh haha we're rich! Of course we can, woohoo!" process going on in my mind and it's super awesome. I feel so decadent, so lavish! I'm buying a sandwich!
To me, that's the definition of "rich". Buying a sandwich that someone else made, anytime I want.
If you're rich enough to be able to buy whatever at the supermarket, or get your favorite sandwich for lunch without worrying about the cost, cherish that. I don't really believe anything from here to private jets is going to make me much happier in practice, but I never want to be below that bar again.
