Writing massive amounts of text also helps with self-estimation as a person who can write arbitrary amounts of text. My evolution as a writer started with me going “meh, I can’t finish anything, I have all these ideas that I sometimes start but then I lose interest after a few pages”. Then I started writing collaboratively with a friend, which was so much fun that I could say, “I like writing, at least of this kind, so much that I was on Utah time in Scotland to stay up and write more, for as much as seventeen hours straight.” Then I wrote a finished novel… it was fanfiction, but I already considered worldbuilding my strength and character creation also on said list. Then I did it again. At some point I started being “a writer”, who can decide to do things like “write a book” and have books exist as a result of this decision.
