Anyone Ever Find a Publisher for a Book (non-automotive) They Wrote?

That sounds familiar. I sent out three manuscripts to persons I have known for decades in order to receive a little feedback: a Catholic priest, a god-daughter, and a dentist who studied auto shop with me in community college. No-one has ever gotten back to me! I guess we are both on our own. I imagined it would be difficult to stimulate some interest, but after thousands of hours of writing and re-writing, it is discouraging to have zero to show for it.
You have the book itself to show for it.

Many artists (and authors) starved throughout history only to have their works valued years later.

Art and writing are about the creation of the finished work that reflects our passion...not about the commercial value. All those starving artists kept going, compelled to create, even if it didn’t bring immediate financial reward.

Picasso used to sometimes pay for his lunch with a drawing on a napkin or menu because it was all he could offer as payment...and yet today his works are valued into the millions of dollars.
