This document provides an introduction to the concept of "becoming unstoppable" by overcoming barriers to taking action. It argues that willpower is an inefficient way to achieve goals, and that focusing on what you truly want most, your "wantpower", is a more effective approach. It presents a model of motivation as balancing the pleasures and pains associated with taking action versus not taking action, with the side having more emotional force determining the direction of movement. The key is to understand what factors are holding you back or pushing you forward in order to direct your "motivation car" in the direction of your highest priorities.
