At Google, I ran a daily team meeting tackling the onslaught of issues arising during a critical pre-launch period. It was depressing. We all ended the meeting looking like we’d been hit by a bus. I knew I needed to change it, so added a standing intro agenda item — “F*ck Yeahs!” We went around the horn and shared all the great things that had happened in the past 24 hours. Everything from signing a new partner to our favorite cheese being restocked in the micro-kitchens.
