Finish the semester strong. Do not attend next semester unless the virus panic has subsided. You are not getting what you paid for with just online classes. You are right, agriculture is not something to be learned remotely. Find something else that fits your strengths, something that can make you actual money. Something practical, maybe not your dream, and get good at it. Bonus if it does align with permaculture in some way. If you have to switch paths in school to accomplish this, do it. Study business, not necessarily at school. I've seen a lot of brilliant people fail because they just don't understand business. Live with your parents or others if you can and save money. Unless you inherited a big farm, it is going to be hard making a living with a degree in sustainable agriculture. Your desire to have a homestead is admirable, but it will be the school of hard knocks that will waste many of your most critical years. Besides, most everyone needs outside income to make it work. Put it on the shelf for 10 years. 10 years is nothing and it will fly by. Do what most people do, but do it better. Get a normalish job and be disciplined about your money. If you put half the energy into building your profession as you would waste in your first year of messing around in permaculture, you will do amazing. Find permaculture things to get experience with on the weekends and plant a small garden this spring. Make it your hobby. Hold off on having kids until you're at least 25 and don't let bad relationships drag you down. Find someone who brings something to the table if you don't want to be single and don't ignore red flags. You can do everything right and lose all of your hard work to a divorce, trust me, I know. Make friends who share the same dreams and encourage each other.
