Editing should be, especially in the case of old writers, a counselling rather than a collaborating task. The tendency of the writer-editor to collaborate is natural, but he should say to himself, 'How can I help this writer to say it better in his own style?' and avoid 'How can I show him how I would write it, if it were my piece?'

At forty my faculties may have closed up like flowers at evening, leaving me unable to write my memoirs with a fitting and discreet inaccuracy, or, having written them, unable to carry them to the publisher.

I write humor the way a surgeon operates, because it is a livelihood, because I have a great urge to do it, because many interesting challenges are set up, and because I have the hope it may do some good.

I drew pictures rapidly and with few lines, because I had to write most of the pieces, too, and couldn't monkey long with the drawings. The divine urge was no higher than that.
