Failure is the greatest teacher. Fail fast has been a foundational tenet in Silicone Valley for a while. Try a whole lot of things, learn, make mistakes, learn, repeat. 

Where ever you find yourself get started now. Russ covers what you can do to be more self sufficient in an apartment versus a suburban house with a 1/4 or 1/2 acre lot versus a rural homestead with 5 or more acres. He discusses both what food you can grow as well as the different types of livestock that you can raise in each setting. There is chatter about predator pressure and how to start a raised bed garden on the cheap. Just remember to start. Fall forward fast! 

Please ask questions and let us know where you're at in the process.
