On Sunday I sent out a mass email to 300+ of my closest friends letting them know that I was switching jobs. The resulting email frenzy was predictable. I got lots of emails from friends and colleagues back, and this sparked dozens of exchanges. The damage: I sent about 130 emails yesterday between 10 and 7 pm–including an overwhelming 43 outgoing emails between 5 and 6 pm (or, about one outgoing email every 75 seconds). It was great reconnecting with so many people, but it’s also exhausting!
