I don't really know since I didn't grow up on a farm, and it's all been trial and error for me getting my farm going. The one thing that I've noticed over and over again when looking for help is a lack of motivation to finish anything. Lack of pride in what they are doing, and a reliance on not knowing how to do it without ever trying, as a reason not to do it.
Sometimes I think that's how I was when I was a teenager. I didn't want to do anything, so when I had to, I fought doing it and did as little as possible. It wasn't until the Marine Corps taught me a few things that I grew up.
