There’s a point in nearly every project where moving forward means holding your breath and jumping in over your head. That could mean expanding the scope of a project to require greater expenditures of time and money than you expected to devote to it, and perhaps well beyond what you can comfortably afford. Or, it might mean taking on a fabrication task that is way beyond your level of skill, at the risk of ruining the whole thing. Or perhaps both. And at that decision point, you have to ether fold up, walk away, and write off your losses, or double-down and say I’m all in. And if you choose the later, what happens next is going to be pretty scary.
