How Long Will This Take?

Sometimes it's hard to wrap my head around.

It's such a small structure, so I think, it shouldn't take that long.

Knowing all the puzzles that arose with trailer tiny house #1, however, I think, will this next one ever be finished by late August?

Many things are possible, and a certain kind of thinking doesn't help. Good planning does help. And remembering that you're doing the best you can.
