the idea of "earning" drink is pretty bizarre, when you really look at it.
it's certainly pushed by the booze industry, though...
the idea of "earning" anything for doing something good and necessary for us, by our own choice, implies we're doing something awful, horrid, punitive, and need to be "rewarded".
it's an insane idea, and makes no logical sense whatsoever.
you're already reaping the real rewards: you're feeling strong and have confidence and can go, or decide not to go, on a holiday to Greece. you've earned the choices. the reward of being able to make them.
