Baltasar Gracián on experience

It is better to sleep on things beforehand than lie awake about them afterward.

I am an old man and have known a great many troubles, but most of them never happened.

Mark Twain1835–1910

If you hold a cat by the tail you learn things you cannot learn any other way.
