I don't like green Christmases. They're not green—they're just nasty faded browns and grays. — L. M. Montgomery. Canadian novelist (1874–1942) Christmas
Proverbs are all very fine when there's nothing to worry you, but when you're in real trouble, they're not a bit of help.
It's not vanity to know your own good points. It would just be stupidity if you didn't; It's only vanity when you get puffed up about them.
Anyone who has gumption knows what it is, and anyone who hasn't can never know what it is. So there is no need of defining it.
