Building an entire house while simultaneously working a full time job (so as to be able to afford it) is a fairly ridiculous endeavour that few humans can fully appreciate.
My best buddy build his house next door mostly solo. I put in dozens of hours with him, helping with site prep, material deliveries, some framing, and a lot of the drywall hanging. But he spent 12 months of basically working two full time jobs and not seeing his wife and kids much in order to get it habitable.
Shoot, we hired a contractor for our build, but on a time and materials basis - so you can bet I was there almost every day making sure time wasn't spent on site cleanup or other dumb stuff by our carpenters at their full hourly rate. And then I did allllll the interior finishing to save costs further. It was a long year.
This thread is on a whole 'nother level of persistence and commitment. Kudos.
