Right on, Joel! The vast majority of wannabe gardener/farmers that I've worked with never accomplish their dreams because they want to "get it right" the first time around. They prep for years and never get their first step taken. And I've had some student gardeners at the community garden quit because "we can't do it right", thus they never stick around to learn how to grow food.
By the way, I'm proud to say that my homestead was created one failure at a time. I've learned an awful lot along the way and managed to survive during the learning process. Heck, I'm still experimenting and learning by my "failures".
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
