Call it a sabbatical and it suddenly makes sense
Had to take TED talks off my Google page a while back because they were just taking too much of my time. This one is 17 precious minutes long, but definitely worth sitting still for: Stefan Sagmeister talks about time off as not just personally rewarding, but economically sensible, too. A few fun project overviews near the end, so don't miss them! Thanks to @wolflow for recommending.
