esa9000 's review for:

The Slight Edge by Jeff Olson
4.0

This could be the most important book you will ever read. You should read it.

So why only four stars? It has some minor details that should be checked. Such as: he refers to the "10,000-hour rule" (do anything for 10,000 hours and you'll become a master in it) introduced by Malcolm Gladwell in [b:Outliers: The Story of Success|3228917|Outliers The Story of Success|Malcolm Gladwell|https://images.gr-assets.com/books/1344266315s/3228917.jpg|3364437]. The problem is that Gladwell got that all wrong form Anders Ericsson's research, which pointed out that in average masters in their fields have devoted roughly 10,000 hours of deliberate practice in their field of mastery by the age of 18 (or so), not that doing anything for 10,000 hours will automatically make you an expert (think of all the people driving every day to work: they have done it for 10,000 hours but they are definitely not masters in driving). See: [b:Peak: Secrets from the New Science of Expertise|26312997|Peak Secrets from the New Science of Expertise|K. Anders Ericsson|https://images.gr-assets.com/books/1445050174s/26312997.jpg|46312952] by Anders Ericsson & Robert Pool.

Anyway, read it.
