When was the last time you were bored? For me, it was in a meeting. And my mind did what it always does when bored -- wander. I doodled. I came up with a few poem ideas. I wrote opening lines for a novel while smiling and nodding dutifully at the meeting leader.
If familiarity breeds contempt*, boredom breeds creativity. Release the need to fill every moment with activity. Relax. Be bored. See what happens!
*Reminding me of the ever-popular take on this: Familiarity breeds.
P.S. for any clients who might read this: No. It was not your meeting.
