Ideas Built From Experience.
Some projects start with a problem that needs solving. Others start with a story worth preserving. These are the things I’m building from decades around trucking, heavy equipment, construction and real-world work.
The common thread
Build Something Useful.
Whether it’s a calculator, a website, a book or a piece of practical content, the goal is the same: turn experience into something another person can actually use.

What I’m Building
Book project
Mother Trucker
A book in development built from decades of trucking, heavy equipment, memorable people, photographs, lessons and stories from the work.
THE BOOK →Experience hub

Photo & Story Archive
Years of original trucking and equipment photographs are being organized to support future stories, articles, book material and historical content.
ARCHIVE IN PROGRESSBuilt to grow
One Project Can Feed the Next.
The same experience can become a useful calculator, a practical article, a photograph with a story behind it, or a chapter in a book.
As these projects develop, this page will serve as the central place to find them and follow what comes next.
“Experience is worth more when you can put it to work.”
