Peak: Secrets from the New Science of Expertise by Robert Pool, Anders Ericsson

4.0

If you have ever heard of Malcolm Gladwell's rule of 10,000 hours of practice to become an expert, this book predates it and is the source for Gladwell. While the rule isn't completely accurate, what is clear from the research of Ericsson is that it does take a lot of practice to get really good at something. But it is more that, it is about the way you practice, the delibrate practice with a focus on specific skills and techniques that are honed.
