I think this is why the #freewrite works so well for me. I can just write something for five minutes and then feel like I've been productive and that feeds my desire to do MORE.
I used to use this technique with my kids for cleaning, too. We'd set the timer for 30 minutes of cleaning and clean as hard as we could for 30 minutes, then have a break. We got SO much more done that way, because they knew that it was only 30 minutes.
Great post and I love the idea of incorporating this even more into my writing process!
