Grit by Angela Duckworth
In Angela Duckworth's New York Times' bestseller, Grit: The Power of Passion and Perseverance, she states, "If doing something repeatedly might be considered practice, deliberate practice is a different animal: it’s goal directed, often solitary, and consists of repeated striving to reach beyond your current level of performance."
On page 123 of the book, she addresses the question: How can you get the most out of deliberate practice? I think that her requirements connect well to the Sprint routine.
Each of the basic requirements of deliberate practice is unremarkable.
a clearly defined stretch goal
full concentration and effort
immediate and informative feedback
repetition with reflection and refinement
Make it a habit...figure out when and where you’re most comfortable doing deliberate practice. Once you’ve made your selection, do deliberate practice then and there every day. Why? Because routines are a godsend when it comes to doing something hard….when you have a habit of practicing at the same time and in the same place every day, you hardly have to think about getting started.
Change the way you experience it.
On page 127, Duckworth recommends that early elementary school teachers model "emotion-free mistake making." Building the Sprint Routine explores this idea in more depth.
