Don't know it all

(1954 July 12)

We are glad to hear you are working hard [nights] on your thesis, the work behind the [day] job. I am cheering for you. I, too, would be fed up on what happened in 1225. And I think that the sooner you start teaching to see if you can teach and if you like it and are liked, the better for you, and learn more later on if you find (just killed a silverfish) you can't get along on what you already know.
