Thank you for considering buying our book, Personal Science: Learning to Observe.

The book presents a step-by-step approach to exploring your personal questions with empirical methods.

It contains no advice whatsoever on what treatments or medicines or diets or vitamins or exercises are worth trying. Instead, it offers meta-advice; that is, advice on how to know if the things that you try actually work the way you expect, and advice about how to develop reasonable new ideas of things to try.

The goal of releasing this LeanPub version is to get the almost competed draft into the hands of people in the Quantified Self community and others who are keenly interested in the topic, so we can hear about what we may have gotten wrong and fix it. There is a minimum price of $8, and the entire purchase price will be devoted to maintaining self-research community resources, such as the show&tell archive at quantifiedself.com.

To comment, join the Personal Science Book discussion at forum.quantifiedself.com, send an email to gary@quantifiedself.com, or tweet at @quantifiedself.

We appreciate your support!
