The Practicing Mind (2006) by Thomas Sterner is a book about how in order to practice and improve at things we need to slow down, concentrate on what we’re doing and put effort into improvement.
Sterner is a piano tuner who describes how he learnt music, works and learned golf. He puts in to the four s words of simplify, small, short and slow. Simplify a task by breaking it down, make small goals on the way, do short amounts of deliberate practice and actually work on them slowly and deliberately and more will get accomplished. He emphasises the process rather than the conclusion and puts an emphasis on skills.
It’s a good short book that makes many valid points. A good, quick, read.
