The majority of people don't have that luxury, and very few have it throughout their whole career. The lucky ones should be grateful this label does not apply to them and not feel insulted by the less fortunate.

Or you should realize that it's called work because it's not fun and you can still enjoy and appreciate it. You think only people with rare amazing unicorn jobs enjoy work? Go drive a cab. Bartend. Work long hours for a startup you care about. Yes you can complain it sucks, but that's why it's called work. Learning how to enjoy it is the same as learning how to be good at it - and better at life.

This luxury you speak of as if it exists in some jobs is completely in your own mind.

Put another way, the only thing preventing you from enjoying that luxury right now, whatever you do, is a shitty attitude.
