How long do you think you could go without complaining? Nothing, not even a whisper of a criticism about your best friend’s hideous shoes or gossip about the new neighbor’s noisy teenagers? A day? An hour? How about 21 consecutive days? I didn’t know what was in store the day I pulled an audio book called A Complaint Free World off the shelf at the library. I only needed something to listen to on a road trip, not a gauntlet thrown at me. But I accepted the challenge and took the next 125 very long days to reach the requisite 21 days.
