"Take an old man's word; there's nothing worse than a muddle in all the world. It is easy to face Death and Fate, and the things that sound so dreadful. It is on my muddles that I look back with horror - on the things that I might have avoided. We can help one another but little. I used to think I could teach young people the whole of life, but I know better now, and all my teaching of George has come down to this: beware of muddle."
