Excerpt from a Speech by Bill Watterson @
Kenyon College, Gambier Ohio, to the 1990 graduating class.

"It's surprising how hard we'll work when the work is done just for ourselves. And with all due respect to John Stuart Mill, maybe utilitarianism is overrated. If I've learned one thing from being a cartoonist, it's how important playing is to creativity and happiness. My job is essentially to come up with 365 ideas a year.
If you ever want to find out just how uninteresting you really are, get a job where the quality and frequency of your thoughts determine your livelihood. I've found that the only way I can keep writing every day, year after year, is to let my mind wander into new territories. To do that, I've had to cultivate a kind of mental playfulness.

We're not really taught how to recreate constructively. We need to do more than find diversions; we need to restore and expand ourselves. Our idea of relaxing is all too often to plop down in front of the television set and let its pandering idiocy liquefy our brains. Shutting off the thought process is not rejuvenating; the mind is like a car battery-it recharges by running.
You may be surprised to find how quickly daily routine and the demands of "just getting by: absorb your waking hours. You may be surprised to find how quickly you start to see your politics and religion become matters of habit rather than thought and inquiry. You may be surprised to find how quickly you start to see your life in terms of other people's expectations rather than issues. You may be surprised to find out how quickly reading a good book sounds like a luxury."

At school, new ideas are thrust at you every day. Out in the world, you'll have to find the inner motivation to search for new ideas on your own. With any luck at all, you'll never need to take an idea and squeeze a punchline out of it, but as bright, creative people, you'll be called upon to generate ideas and solutions all your lives. Letting your mind play is the best way to solve problems.
For me, it's been liberating to put myself in the mind of a fictitious six year-old each day, and rediscover my own curiosity. I've been amazed at how one ideas leads to others if I allow my mind to play and wander. I know a lot about dinosaurs now, and the information has helped me out of quite a few deadlines.
A playful mind is inquisitive, and learning is fun. If you indulge your natural curiosity and retain a sense of fun in new experience, I think you'll find it functions as a sort of shock absorber for the bumpy road ahead.

So, what's it like in the real world? Well, the food is better, but beyond that, I don't recommend it.
