A man who will not get scared on some occasions, lacks good sense.
There is no such thing as a convincing argument, although every man thinks he has one.
Instead of loving your enemies - treat your friends a little better.
A poem is no place for an idea.
Don't take up a man's time talking about the smartness of your children; he wants to talk to you about the smartness of his children.
When a friend is in trouble, don't annoy him by asking if there is anything you can do. Think up something appropriate and do it.
