According to my daughters, my most irritating habit is asking for cups of tea.

You can't trust other people. If it's important, you have to do it yourself.

When I started out, there were a lot of things I knew I couldn't do, and a lot of things I only found out I couldn't do by going and doing it. And no-one was watching, and nobody cared.

I decided that I would do my best in the future not to write books just for money. If you didn't get the money then you didn't have anything. If I did the work I was proud of and I didn't get the money, at least I'd have the work.

You're always you, and that don't change, and you're always changing, and there's nothing you can do about it.

I would feel infinitely more comfortable in your presence if you would agree to treat gravity as a law, rather than one of a number of suggested options.

Nothing I did where the only reason for doing it was the money was ever worth it, except as bitter experience.
