This is Jack Dorsey's personal user guide, similar to the manual for a coffee machine or vacuum cleaner.
It helps you understand Jack's way of working, build a strong relationship and get things done faster, both at work and in your personal life.
It allows you to shorten learning curves, build on strengths and compensate for weaknesses. Working together in this way can lead to exceptional results and, most importantly, build mutual trust.
The personal user guide covers five aspects of Jack Dorsey and is based on the Big Five personality model.
