He is happiest of whom the world says least, good or bad
When we were doing 'Freaks and Geeks', I didn't quite understand how movies and TV worked, and I would improvise even if the camera wasn't on me. I thought I was helping the other actors by keeping them on their toes, but nobody appreciated it when I would trip them up. So I was improvising a little bit back then, but not in a productive way.
So much for industry, my friends, and attention to one's own business; but to these we must add frugality if we would make our industry more certainly successful. A man may, if he knows not how to save as he gets, keep his nose all his life to the grindstone, and die not worth a grout at last.
