I have a terrible work / non-work balance, and one trivial habit I've established is turning off my (Mac mini & MacBook Air) computers & screens when my work time is done. I don't want it to be trivially easy for me to just do one more thing…there be dragons. My Saturday mornings are more often markers for running Onyx[1] for maintenance.
