Others that come to mind from the book: her writing on "one-inch picture frames" and on "radio station KFKT", which I found to be very helpful around imposter syndrome.
It's a very entertaining (and easy!) read packed with a lot of advice that I've found more useful over time than I imagined. Recommend picking it up if you're looking to meander a little in your reading. It's a good journey.
By the time I start a second draft, it is often from scratch, with elements from the first brought in. It is far more coherent and organized, and may move in a radically different direction than the first draft did.
You iterate depending on how important and big this is. For something short, two drafts or so is fine. When I did some legal stuff (not a lawyer, but making some important legal filings) I did many drafts and outlines.
But that act of the first linear writing to get your brain marching is a key first step.
What's 1995 about this? The PDF was distilled in 2006 and includes a reference to a 2005 publication. The intro says the actual body text is from a 1994 book.
