"For concentration," I said, "you need a cat. Do you happen to have a cat?"
So I passed him some very good advice that if you want to concentrate deeply
on some problem, you should acquire a cat. Alone with the cat in the room
where you work, I explained, the cat will invariably get up on your desk and
settle placidly under the desk-lamp. The light from the lamp, I explained,
gives a cat great satisfaction. The cat will settle down and be serene, with
a serenity that passes all understanding. And the tranquility of the cat
will gradually come to affect you, sitting there at your desk, so that all
the excitable qualities that impede your concentration compose themselves
and give your mind back the self-command it has lost. You need not watch the
cat all the time. Its presence alone is enough. The effect of a cat on your
concetration is remarkable, very mysterious.
