"But then you become closed. Then you start dying as far as your intelligence is concerned because intelligence needs the open sky, the wind, the air, the sun in order to grow, to expand, to flow. To remain alive it needs a constant flow; if it becomes stagnant it becomes slowly slowly a dead phenomenon."

make it a practice to avoid hating anyone. If someone's been guilty of despicable actions, especially toward me, I try to forget him. I used to follow a practice - somewhat contrived, I admit - to write the man's name on a piece of scrap paper, drop it into the lowest drawer of my desk, and say to myself: "That finishes the incident, and so far as I'm concerned, that fellow." The drawer became over the years a sort of private wastebasket for crumbled-up spite and discarded personalities.
