Another newbie here, this time one with a confirmed diagnosis…it’s NOT gas…

So, if I may, a few not-necessarily-related observations…
I’m a writer who lives on the Gulf Coast of Texas. This forum is awesomastic. I sometimes make up words as I go…and…I have one question already…
I know there have to be rules somewhere concerning the dreaming of, planning for, and sweat producing stages of building a T or TTT. At what point can I (officially?) say I have begun my build?
When I clean out a corner of the shop? Drive the first screw? Spend my first dollar? When I convince my wife it’s a great idea? When I choose a name to call her?
(the trailer, not the wife).

What’s the consensus about when I can say I’ve begun?
