Too much of anything is a mistake, as the man said when his wife presented him with four new healthy children in one day. We should practice moderation in all matters.
Moderation in all things. And even moderation in moderation. Don't get too much moderation, you know?
Observe moderation [or: Keep balanced]. [Halt Mass!]
This was an old principle of Aristotle's.
Do nothing immoderate.
