His original essay is here.
A few favorites (all quoted):
- Write a bad version 1 as fast as you can
- Expect 80% of the ideas in an essay to happen after you start writing it, and 50% of those you start with to be wrong
- …just say the most important sentence first
- Read your essays out loud to see…which bits are boring (the paragraphs you dread reading)
- Write for a reader who won’t read the essay as carefully as you do
