湿布を貼らにゃいかんのは「腰」じゃなくて「心」

It is your mind that needs healing. Not your back.

天才に限界有り。努力に限界なし。

Natural talent has limits; but there’s no limit to hard work.

備えあれば憂いなし

A stitch in time saves nine.
This is the saying that came to my mind
when I had a little chat with my student today.
He came in a mask,
so I said, "Got a cold, sir?"
He said, "Oh, it's for prevention."
I said, "Ah! A stitch in time saves nine."
He smiled and went into his classroom.

老いを謳歌せよ！

You're Only Old Once! (by Dr. Seuss)

十人十色

Your strong point is different from my strong point. My strong point is different from your strong point.

やり直しは何歳からでも・・・

Today is the first day of the rest of your life.
