"The worst thing you can possibly do is worrying and thinking about what you could have done" — Georg Christoph Lichtenberg

Don't think there are no crocodiles because the waters are calm

When I was younger, I could remember anything, whether it happened or not.

Age is strictly a case of mind over matter. If you don't mind, it doesn't matter

If everyone is thinking alike, then no one is thinking

To imagine is everything, to know is nothing at all

It is impossible to open a book without learning something
