The gap between tasks is sometimes what makes both tasks possible.

Empty stretches look like waste on a calendar, so they are the first thing removed. What actually happens in them is that the last thing finishes settling and the next one gets a chance to begin properly. Take them out and the meetings blur, the notes never get written, and you arrive everywhere carrying the previous hour.

Look at tomorrow and leave one deliberate space of fifteen minutes between two things that matter. Do not fill it with a small errand. Notice whether the second thing goes better.
