...That one thing is learning the art of making money. With money, all of your other problems go away, and making money is just about as easy as falling off a log.
If I was in your situation, I believe I would spend a week learning how to make money, a week making money, then get the whole works built by a professional. Let me give you a few hint's...
Santa Claus's get paid $100+ per hour... So do clowns, mimes, face painters, and many other types of entertainers. Even street entertainers can make $40-$60/hour or more.
I'm selling Christmas Trees. I make a lousy $10 per tree. In the last 7 days I have cleared $7500, and this gig will last through Christmas.
If you have some artistic abilities, business window painters make a killing this time of year.
Learning to make money, anytime, and anywhere, will get you further in life than anything else. Once you have learned that, your wood gas project or anything else money can buy becomes easily obtainable. Spending your time learning to make money, then making that money, will get your project completed quicker than any other way.
Go make the $1,000 you need at a flea market this weekend. Do you know how? Other people do it EVERY weekend. Swap meets and Christmas bazaars can be a gold mine if you know what you're doing. A friend made $5,000 last weekend at a Christmas Bazaar, selling advertising to the vendors. Oh please elaborate on this money pulling oppurtunity!
If you don't like dealing with the public in person, then learn to make money online. Free software and a mailing list could have 1,000 people paying you $10/mo within a week or two. Please elaborate how this is accomplished legitimately! People do this stuff all the time. I could pull $10k a month out of your town starting next week if I wanted to, and you could do the exact same thing and the same people would gladly pay you too. I know areas where over 100 people are doing this, and all of them are making that kind of money., I've become jaded on internet work, seen too many scams & schemes plus entry-level online gigs like AMAZON Mechanical Turk or surveys pay peanuts. Not to mention the there is always somebody else on the internet willing to work that same gig for less. I know four digit internet income takes work, so please share your legitimate internet-based work Off Grid 24/7.
How many of those above jobs require Social Connections? Because that is one thing that is very unobtanium for me.
I spent over 40 years of my life working regular jobs because that was all I knew. I only learned how to actually make money after I retired. You have youth on your side, learn how to make money, you will never regret it.
