Re: Housing
I'm not sure which two people you're referring to, but I assume I'm one of them. If so, I'm not sure it makes sense. There are lots of problems that living a hard life would have on someone wanting to get into electronics. The most obvious one is that, when you start to work on electronics, you'll break a lot of things. It's one reason I am mostly a software person, not a hardware one. When I was a child, when I messed up a program, at worst I had to restart the computer before I could get to fixing it. I never had to buy anything as a result of messing up. Just working on electronics requires you to have tools and parts that cost money, and each mistake will be more costly still. Another big one is access to guidance, which is much easier if you can find someone to teach you, and you're more likely to have such a person in a well-resourced school than if you don't have that. These are all major problems. House size, however, is less of a problem. I wasn't saying that anyone can get into electronics, but that as hobbies go, it's less limited by available space.
There are lots of ones that are more limited in that respect. Woodworking, for example, will not work very well if you don't have somewhere relatively large in which to store things. The tools are quite large, the stuff you're working is as well, it generates a lot of byproducts that you don't want to have inside. Or car repair and maintenance. You can't do either of those on a bedroom desk. You can do electronics work there. Living a hard life is an obstacle to all of these. Living in a small place is an obstacle to only some of them.
