The cost of interrupted work (2023)

I’ve been saying for years that an interruption costs me _at least_ 15 minutes.

Knowledge work is not the same as physical work. Both are noble in my opinion, but not the same.

Knowledge and physical work is not the right distinction. It's fine for two broad categories, but within knowledge work there is — at the very least — the manager vs. maker schedule.

Thought work, knowledge work, physical work, then? Probably more layers here, of course.
