My family owns multiple cabins, mostly built by family members with the occasional framing and finishing work by friends of the family and/or a local contractor. The one my father owns was framed and roofed by contractors, but the closing, finishing, deck and float construction, and 30 years of repairs and renovations were done by himself and us kids. It sits on a steep hill, so putting a 60x20ft deck on 15ft stilts…
Now I write software and I work with a lot of people who dream of going off in the woods and building a cabin, as though it's the same as building software. I have to remind them that "there is no undo". "Measure twice, cut once" is a phrase for a reason. You can't refactor your cabin half way through building. Surprisingly many of them never even considered these things, let alone the tricks or techniques needed to do a good job.
I think a lot of white collar workers see what blue collar workers do as perhaps difficult physically, but not mentally. But that couldn't be further from the truth. And this is especially true when you're trying to piece together an entire cabin by yourself.
