I would do everything just the exact opposite of what I did. I've experienced this life, and it's been a good life, and it will be for many more years. I have no regrets, and I've learned that I could survive if everything suddenly became just the opposite.
I'd be a stay-at-home mom with 10 children. Home-schooling. Living way out in the middle of nowhere. Raising our own food. Generating our own energy. Making soap. Sewing clothes. Building fences. And every night we would all play music together!
