Any tips on setting up a situation where I can eventually live off the land?

I am a 22 year old student finishing an outdoor adventure skills program, and I want to save up money to buy a piece of land and live off of it with my girlfriend. I need help on how to do this, I need tips from people who have done this or are doing similar research and want to be more sustainable and self sufficient. I want to experiment growing my own food, gathering energy from the sun and wind, making shelters, and cooking, and more! I have books, I've done a lot of research; I have ideas, I just need to make a plan of some sort. I know I'll know I need money, I still even have my lovely student debt to pay off. I was just hoping for some advice, so I AskReddit, got Anything?
