Do, every day, something no one else would be silly enough to do. It is bad for the mind to continually be part of unanimity. Man's mind stretched to a new idea, never goes back to it's original dimensions. An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't.
Imagination is more important than knowledge.
Knowledge is limited. Imagination encircles the world. I hear and I forget. I see and I remember. The unexamined life is not worth living.
