Depletion results from so many triggers: grief, worry, overwork, no work, conflict with friends and family members, overeating and undereating, too much exercise and, for most of us, too little. Sometimes the cause slams into us like the fast-moving service vehicle that recently rear-ended my car on the freeway from following too close. When an accident happened in front of me, and I was able to avoid colliding into it because I’d left enough space, the driver behind me had not. Stopped dead in my tracks turned out not to just be a phrase. That impact depleted me in multiple ways and forced me into cutting back my schedule.
