> there's a level of cost below which I can just buy something on a whim without worrying about whether I can afford it at all, and above which I need to think about it for a minute. When I was in college, that level was about $10. It was a kinda weird transition when I got my first professional job out of college, and I had to get used to that threshold being closer to $1000 instead. And then you get two kids and a mortgage, and that threshold drops like a comet into a neutron star.
