So I've already written my first novel, and my second, and my third, but that doesn't mean I don't still love to leanr how other people write. I still have a ton to learn myself!
Joanna Penn, the author of Pentecost, has a great entry in her blog about writing your first novel.
One of the pieces of advice I love is to write the first draft as quickly as possible, then focus on the rewrite.
I have long said "Get it written, then get it right". That first draft is hard to find time for. It interrupts our lives. It feels pointless at times, but once it is down, then you have written a freakn' book! Polishing it feels less fruitless and more like meaningful work.
