"Everything in Moderation"

I hate when people say that. It's impossible to have everything in moderation, because if you were to have everything in moderation, that would include having moderation in moderation. But then everything wouldn't be moderate. So you can either have everything except moderation in moderation, or moderation and a moderate amount of things in moderation. "Everything" includes moderation, after all.

I suppose you could be consuming, living in moderation for most of the time but at certain times engaging in excesses.

Moderation in moderation.

Moderation is logarithmic.
