"If there is something to pardon in everything, there is also something to condemn." — Friedrich Wilhelm Nietzsche

Be careful about reading health books. You may die of a misprint

Anyone who has never made a mistake has never tried anything new

A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing

Great emergencies and crises show us how much greater our vital resources are than we had supposed.

Don't take the wrong side of an argument just because your opponent has taken the right side.

Never interrupt your enemy when he is making a mistake
