Simplicity is the keynote of all true elegance.
Don't spend time beating on a wall, hoping to transform it into a door.
Don't take life too seriously. Punch it in the face when it needs a good hit. Laugh at it.
What is real and what is not is for your heart to decide and for your heart to know.
Forget injuries, never forget kindnesses.
By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.
