My recent list of ideas to help make a good life seems to be missing an important one, one that I have used often and that has a very long history: "Everything in moderation". The logical question those words can prompt is"Should I apply that idea in moderation?" Maybe there should be one or two things I don't do moderately?
I didn't know until looking up the idea with Google that the apostle Paul quotes the principle in his letter to the Phillipians.
When I tire of something, I can quote that idea, a fundamental one with ancient Greek thinkers. Doing that gives me the idea that I am being smart and well-rounded.
