The farmer's market I attend is located in a University town. Go Aggies!!! One day a lady came to market, and she says to me, "What? -- are your credentials? -- to be a farmer?" I laughed in joy, spread my arms wide to encompass two tables full of beautiful, better than organic vegetables, and I replied, "My resume is displayed on the table in front of you." LOL! That pretty much made my year as a farmer.
I highly discourage anyone from going into debt to "get an education". In my estimation, it's not smart to graduate from university with hundreds of thousands of dollars in debt. I think that the smartest people are those that go directly into the workforce, or that attend a trade school.
I would recommend a trade that might be useful in a homesteading community... Farming, animal husbandry, welding, irrigation, etc.
There is always a tension between earning money off-farm, and settling into homesteading habits that minimize the need to earn money. I see a lot of people trying to do what I think of as half-homesteading. They want to hold onto the new car, and a house payment. Then they need a job to pay for them. Then they don't have the time to do homesteading properly, and they have to pay for things that a homesteader would be creating on-farm. If/when I ever do homesteading, I expect to ditch the car, the house, and the farmer's market. If people want to buy vegetable from me as a homesteader, they can come visit.
