Apparently making a list to avoid so many things to do makes you 4x more productive https://medium.com/@aissypewdiepie/instead-make-a-not-to-do-list-89f8ce2bbdc5
Anytime I start a new project, I always make a list of "anti-goals." These are things that would be cool to do and maybe valuable at some point, but are ultimately distractions in the now. Pivotal (www.pivotal.io) does this with client engagements, which is where I learned the habit. It's a good one!
