Check out this essay I found at paulgraham.com
Every once in a while (usually several times a day in my case, as it happens), you read something that makes you think: “Yes, that’s it; that’s exactly right. I hadn’t thought of it before, but that’s just the way it is.”
Reading this essay gave me one of those moments to such an intensity that I thought, “My students really need to read this.”
So please do read it, and tell me what you think.
