I recently got back from a month’s vacation — the longest I’ve ever taken, and a shocking indulgence for an American. (Earlier this summer, I was still fretting about how to pull off two weeks unplugged.) The distance, though, helped me hone in on what’s actually important to my professional career — and which make-work activities merely provide the illusion of progress. Inspired by HBR blogger Peter Bregman’s idea of creating a “to ignore” list , here are the activities I’m going to stop cold turkey in 2012 — and perhaps you should, too.
