4 days of no email or phone can do your head in. So I wrapped it around Mihaly Csikszentmihalyi's "Flow". (Prizes for anyone who can pronounce the author's name). Michael Crooke, the CEO /President of Patagonia got me into it. He is taking a one year sabbatical to finish up his PhD on the subject. The book asserts that being in flow is somewhat like sports people in the "zone" - a place where they are at peak performance, so much so that they lose track of time. These are optimal experiences. The book digs into how to get in that state in every day life and at work. Fascinating!
