You've got to be brave and you've got to be bold. Brave enough to take your chance on your own discrimination, what's right and what's wrong, what's good and what's bad.
If you remember only one thing I've said, remember that an idea is a feat of association, and the height of it is a good metaphor. If you have never made a good metaphor, then you don't know what it's all about.
The sun was warm but the wind was chill. You know how it is with an April day. When the sun is out and the wind is still, You're one month on in the middle of May. But if you so much as dare to speak, a cloud come over the sunlit arch, And wind comes off a frozen peak, And you're two months back in the middle of March.
