Maya Angelou famously wrote in hotel rooms. When working on a book, she’d reserve a room and live there for as long as it took to finish. Writers know how to carve out time for deep work. A romance author I saw interviewed said she always wrote for an hour in the morning before going to work at her full time job. Another author shared how she writes with the podcast Writing Excuses: thumbing snippets on her phone whenever she can snatch a few minutes, such a commuting on the subway! She said she’d written entire books this way.
I think any style of deep work can work for a person as long as they feel ownership over it — “this is my method; it works for me!” — and are consistent with it.
