There is more to say about the value of friends than just one short post, but it's worth making a quick start on it. One of the things I've been working on is a finished room in one of our outbuildings to use as an art studio/sitting area. This particular space was one of the big draws of our place, and was something we were enthusiastic about when moving in. Unfortunately there has been a bit of a debacle with the local building inspector, and things have gotten slowed down by 3 months. Unsurprisingly then when things started moving again, I wanted to get things done as fast as possible. To that end, when I had to insulate 800 square feet of ceiling, I called in friends.
Two friends showed up on 3 day notice, and helped out with the rather unpleasant job of doing ceiling fiberglass insulation. It was a learning experience for both of them which may be valuable to one of them who has been doing work on her own house. That said, both of them were covered in fiberglass and itching thoroughly by the time it was done. The value is obvious, I have friends, they showed up and helped cutting down the time this took significantly. It meant that I got that 800 square feet done within 5 hours rather than 15, or more. Not only that, neither of them asked to be paid (which I can't afford right now). They just know that if they need a hand, I'll come give it if I can do so at all.
Chances are over time, you will make acquaintances and friends with a variety of skills and abilities. As you homestead draw on those skills and abilities. Chances are you don't know how to be a plumber, an electrician, framer, finisher, floor installer, foundation layer, insulator, painter, excavator, lumberjack, farmer, animal expert, butcher . . . etc. Use the people you meet to learn what you can, and get done what needs to get done. Chances are you can do something that they can't and need done, or you can simply offer your time and labor helping out. Don't be afraid to help folks out "for free." In the end it will end up coming back and helping you when you need to reach out for help.
