FU money is also owning the island.
You control who gets on the island, and who isn’t. You get to choose who you work with, who you partner with, and which customers you’ll serve (and which you won’t).
You get to do whatever the hell you want on this island! Work the way you want, in whatever style, have as much fun, with other people who enjoy similar things.
I also work for a profitable tech company, and love it. There is no other type of company I would rather work for, than the ones that are concerned with making money. Something that Warren Buffett would invest in (if he studied and understood tech). Love the path that you and DHH chose. It’s not the popular one, but it’s the right one.
