Ah, I see. But what does it mean? An aphorism has an underlying principle of (practical) wisdom.

Then I guess I didn’t put one forward after all. Maybe it just means whatever you get out of it.

Just like anything else.

What do you get out of the aphorism you provided? I guess, I am just not understanding it yet. Is it the idea that we should strive towards being with those who think differently than those who think the same?

Told you already: a contradiction on the one hand or a self-deprecation on the other.

Pick a kind of person for yourself, see which one works for that person.

I picked jackass, in which case I wouldn’t want to join a club full of jackasses. But being one, I should love to be a club full of them. Hence the contradiction.

On the other hand, when I pick Super Dad for myself, to join a club full of Super Dads puts me at risk of being too competitive, in which case I would have to lower my standards. But I wouldn’t lower my standards, which is a form of self-deprecation, hence would not want to join a club that may foist that upon me.

I picked jackass, in which case I wouldn’t want to join a club full of jackasses. But being one, I should love to be a club full of them. Hence the contradiction. — Mww

It's because you like Metallica.
