How practice affects brain function
/Here's an interesting TED-ED video on the value of practice, what makes good practice, and how practice actually improves brain function. Lots of things can be practiced, from music to knitting to developing a healthier diet or new habit.
Key elements of practice are (nearly) daily repetition, constant curiosity about how to do something better, and working at the edge of a know skill set without jumping in too deep.
Importantly, by going through the process of trying something, messing up or finding room for improvement, and trying again, practicing gives us skills to deal with anxiety in other areas of our lives as well.
