You don’t have to be a famous author to suffer from writer’s block. We all can get stuck in our thought processes and mired in our actions. That's true for leaders and managers as well, explains Adam Alter, a marketing professor at the NYU Stern School of Business. He has studied how people hit plateaus or roadblocks in their work and careers. And he shares different methods for breaking free, including one proven tactic that seems very wrong: doing nothing. Alter wrote the new book Anatomy of a Breakthrough: How to Get Unstuck When It Matters Most.
