How It Connects to a Larger Goal
A free playbook is a start, not a finish. The real leverage comes from doing one small thing every single day — not from one heroic push. That's exactly how the 28-day method works: 28 consecutive days, each one small enough to finish.

The behavioral-science research that shaped the method.
Worksheets, templates, checklists, planners, and guides — all free.
