David Happe

Welcome to my Amazon author page.

I wrote The Retail Sales Playbook to share the wins, losses, and hard lessons from that journey in plain English for people who want to grow faster and make fewer mistakes. I also wrote Launching Points, about succeeding without a four-year degree, and Vigilant Kids, on teaching children street-smart self-defense.

Written for the person who wants more control over their future but cannot afford chaos, this book offers a grounded framework for building a business while still employed, reducing risk, and moving toward a carefully planned Freedom Date.
