The Seventy Days of Writing Sweat Challenge has already paid off for me, big time. My first huge lesson: Stay in the work! That's what makes it a w.i.p.! That is: a work in progress.
My w.i.p. that I'm working on for the 70 Days is a book that has ached to get onto the page. A book that I have many, many notes for. Notes on characters, snatches of dialog, plot points, a couple of scenes, etc.
So what's the difficulty? Getting into the "mode" of the w.i.p. on a daily basis--it's waited for long enough that the first rush/impetus/motivation to write it down is gone. I'm beginning to retrieve it, but it takes effort. And since I set the novel aside several times--that's my habit.
Stay in the work!
What do you do with a project that you've set aside and now have returned to? What works for you? What doesn't work?
