The only true wisdom is in knowing you know nothing.

The more I see, the less I know for sure.

Conquering others takes force, conquering yourself is true strength.

There is no friend as loyal as a book.

If you tell the truth, you don't have to remember anything.

When people talk, listen completely. Don't be thinking what you're going to say. Most people never listen.

Never go on trips with anyone you do not love.

You can't get away from yourself by moving from one place to another.

Always go too far, because that's where you'll find the truth.
