Fun, urgent or fear-based
Most of what we do at work all day is one of these three.
Fun: It's engaging, it gives us satisfaction, people smile.
Urgent: Someone else (or perhaps we) decided that this paper is on fire and it has to be extinguished before anything else happens.
Fear-based: Most common of all, the things we do to protect ourselves from the fear we'd have to sit with if we didn't do them.
Not on this list: important.
A day spent doing important work is rare indeed. Precious, too.
