Paul Graham offers some advise about writing
A lot of people ask for advice about writing. How important is it to write well, and how can one write better? In the process of answering one, I accidentally wrote a tiny essay on the subject.
I usually spend weeks on an essay. This one took 67 minutes-- 23 of writing, and 44 of rewriting. But as an experiment I'll put it online. It is at least extremely dense.
