"There is great joy and pride in building something with your own hands, growing things, producing your own fruit, vegetables, milk, eggs on farms...but it is definitely not easy and requires a lot of time and resources."

Absolutely! Instead of working as mad in a gym which is so popular now, I think is much better to build, plant, grow something on your site in free time - work on a fresh open air, seeing as something you are doing is transforming from nowhere to your world - it is wonderful!
I know one couple they are little younger than I am, so they had already built a house, have some cows, chickens, ducks, two children and are making ecological business through the Internet for the main income - sounds great for me.

The knowledge and experience, I think, is more important than resources cause we have a lot. But yeah, youngsters are farther and farther away from the common knowledge what not making them more independent of a situation around, not happier.
