One reason programmers dislike meetings so much is that they’re on a
different type of schedule from other people. Meetings cost them more.

There are two types of schedule, which I’ll call the manager’s schedule
and the maker’s schedule. The manager’s schedule is for bosses. It’s
embodied in the traditional appointment book, with each day cut into one
hour intervals. You can block off several hours for a single task if you
need to, but by default you change what you’re doing every hour.

Very insightful and well written.
