Welcome, fellow Texan! I completely understand your feeling to become more independent of society and their definitions of "success." There's definitely a lot of pressure out there to comform to a certain standard; which, ultimately, doesn't even matter in the long-term scheme of things.
While I haven't completely removed myself from the rest of society, I have been doing a little at a time to become more self-reliant and create my own, personal space where I can foster a lifestyle which benefits my physical and emotional health.
My advice is to start with small projects and slowly work your way into building your ideal environment. For example, make and maintain a
sourdough starter, and use the discard to bake your own breads. Grow some cucumbers and ferment some pickles. Sheet mulch a
garden bed with the goal of growing half a year's worth of green beans for the family. As you achieve these smaller goals, you can build up from them until you have the whole system designed and implemented. Sure, things will go wrong and failures happen; but if you are learning what doesn't work, then it's definitely not a waste of time, and it's easier to go back and try again when you aren't doing too many projects at once.
Fortunately, here in CenTex, we are able to have spring and fall gardens (and can grow some things straight through the winter). This allows us to gain insight on what works best, when and where (and produce a bit more food to get us through the winter).
So glad you found this community and I wish you the best in your new journey!
