As we go about our days, we make tons of decisions, big and small. As Roy Baumeister and John Tierney point out in their book, Willpower, each of these decisions takes up a certain amount of our willpower, which is finite. Once we’ve used it all up for the day, these decisions get progressively harder to make, which makes work and creative efforts more difficult. In this video summary of the book, Fight Mediocrity highlights a few practical ways that understanding the limits of our willpower and adjusting accordingly can have a drastic impact on our productivity, as well as our satisfaction with our work.
