The quality of your life depends on the quality of your mind. Unfortunately, we spend little time improving our thoughts, and it is rarely taught at school. As a result, we go through life without really understanding how to use our mind. We have in our head the most sophisticated object in the world, but we barely know how it works.

In the end, they quit. Luckily, our mind can be trained, and this book will show you how. It combines stoic philosophy with modern psychology, and provides the tools to help you visualize with clarity, act with determination, and resist with discipline.
