Years ago I bought some scrapbooks that were put together by a young woman in the late 1930s and early 1940s when she was starting her career as a school teacher and got married.

Here is one of the things she clipped from a magazine. It refers to Woodrow Wilson's Fourteen Points for peace that followed World War One, and this must have been published when events were starting to lead up to World War Two:

"The Eight Points
These Eight Points, subscribed to by many sociologists, may not be as famous as the historical Fourteen; they are, nevertheless, equally important as a war preventative, either international, sociological, or domestic:

1. Don't contradict people, even if you are right.
2. Don't be inquisitive about the affairs of even your most intimate friends.
3. Don't underrate anything because you don't possess it.
4. Don't believe that everybody else in the world is happier than you.
5. Don't be rude to your inferiors in social position.
6. Don't repeat gossip, even if it does interest a crowd.
7. Learn to hide your aches and pains under a pleasant smile.
8. Learn to attend to your own business. This is a very important point."

It sounds like good advice.
