I'm nowhere near Bill Gates money and never will be.
I think amongst my circle of family and friends, I probably net 3-4x more than the highest earner I know. For the most part, I can buy myself whatever gadgets or books or food or things I typically want.
But...I don't, well, I don't always.
In fact, oftentimes I find myself putting off buying Book A or B because I just don't feel like it's a good use of money right now.
Sometimes I won't even buy myself new socks until all of mine have been worn down to absolute tatters. I own two pairs of jeans and one pair of shoes and they're going to go until they completely fall apart.
Other times, I want this new game and I don't buy it because I can't really justify it for how much time I might end up having for it.
But if anyone I know gets me any of the above or similar, I'd honestly be super happy. It removes that mental battle for me and I get something I actually want / need.
