I recently listened to Episode 64 of The Power Company Podcast. In this episode, the host interviews Trevor Ragan from TrainUgly and the topic of discussion is fixed versus growth mindset. For an introduction to growth mindset, a good place to start is the post I wrote for the Teaching Tidbits Blog called The Role of Failure and Struggle in the Mathematics Classroom. At the end of the podcast, Ragan suggests some further reading. One of those books is The Obstacle is the Way: The Timeless Art of Turning Trials into Triumph by Ryan Holiday, which I recently started reading. The beginning of this book contains the following quote by Roman emperor Marcus Aurelius that embraces obstacles and discourages the fear of failure:

The impediment to action advances action. What stands in the way becomes the way.

Marcus Aurelius
