What Holds Up the Roof: The Four Principles of Entrepreneurship — a book by Michael "Mash" Ashley
The book

Trends come and go. Principles endure.

What Holds Up the Roof is a business fable — the four principles of entrepreneurship, drawn from twenty-five years of building and advising. You follow one founder through routine, loss, and rebuilding, and watch them learn what actually keeps a business standing when the plan falls apart.

  • A story, not a framework deck — you'll finish it
  • Four durable principles instead of this year's tactics
  • Written for founders in the messy middle, not for the case study
  • The same thinking behind every engagement on this site
