Sometimes when things seems to be dragging along and you wonder if you will EVER be able to move into your house, it helps to take a look at the results so far.
We have nearly all exterior walls built. All sheathing is attached. The roof underlayment and rigid insulation is in place. The PV racks are up waiting for their panels. All the concrete work is done (well, except for the basement shower, but we won't dwell on that). The house is looking distinctly house-ish.
I've got a 6 year old who knows how to build a house. He can competently use hand and power tools. He can speak with great authority and curiosity about concrete finishing, framing, and insulation. He's an excellent problem solver at the building site and feels comfortable grabbing materials and tools and building a boat or a crane or a hospital when the fancy strikes.
There are even some positive personal results. I've noted before that the main task of building is Moving Heavy Stuff. While I frequently complain about this fact, I am forced to admit, there are some benefits to all that Moving of Heavy Stuff. I also will add that I've learned A LOT through this process. In many practical ways, more than I did through 4.5 years of college. I've also gotten to put into practical application all that trigonometry, geometry, and fraction math from junior high.
