I started David Epstein's new book Inside the Box and couldn't wait to write about it. The argument cuts against everything we assume about creativity: total freedom doesn't spark it, it paralyzes us. The real breakthroughs come from working inside tight constraints. I look at how deliberate limits force cleaner, faster work, using lessons from Bach and the early days of computing, and how you can build your own constraints on purpose instead of waiting for a crisis to impose them.
