The Contractor Brain
How a working contractor thinks through one jobsite problem, and the tool that actually helps. Tested against real work, limits included.
The rules of the section
- Start with the problem, not the gadget. Every post opens with a real jobsite or office pain that costs time or money.
- Owner’s math. Every tool has to pay for itself: what it costs, what it saves, and how fast it pays back.
- Say what it can’t do. Every tool gets an honest limits section.
- Real sources. Numbers are cited. No made-up statistics.
