What's your favourite "Productivity" hack?

One of mine that I don't think is talked about enough is making something stupidly simple to do. The classic example of this that can be deconstructed and applied to almost anything is: Want to floss more, commit to flossing JUST one tooth. It's hard to talk yourself out of doing that, but chances are once you start, you'll just floss every tooth. Let me know if you have any productivity tips below.
