The only way to build towards a dream like that is two things, imho

1. Save money. Take high paying jobs you may not like much to just save up.

2. Learn. Read books on gardening, on simple living, on maintaining and restoring a home, and watch YouTubers who live the life you want to live and see the downsides of it too. (For the latter, Tyler and Todd might be a good fit, they are building a container home in the middle of the woods and they do show the setbacks as well as the triumphs)
