The Brain Shift Method, Second Edition — book cover

Second edition · Mindset

Seven phrases of change

Most of the behavior you want to change is not a single bad decision. It is a loop: a trigger, a response, a quick payoff, and a cost that arrives late. The Brain Shift Method is a practical, self-directed system for doing something about it — define the loop in four lines, compress it into thirteen anchor words, and write fifty present-tense statements.
