I’ve always been a big fan of an open calendar myself. I’m still waiting for someone to invent a calendar app with a decent “month” view, as that’s the level of granularity with which I tend to think of my time.
Are there any methods you use to reduce mental energy wasted in deciding what to do in the moment? (Such as a habits or rules: write here, do this kind of work this time of day.) Or, do you generally not have trouble deciding what to do in a given moment?
