The “zone.” Flow. Whatever you want to call it, at one stage or another, every one of us aspires to get there. It’s when we do our best work, achieve our peak performance. Last weekend, I competed in the New England Masters Swim Championships, and for the past eighteen months I’ve been co-authoring a book. Both of these are endeavors that rely extensively on an ability to get in the zone; they can truly make the difference between a good day and a great one.
