As others have noted, I think that everyone here wants to see you successful at this, regardless of whether you do this as a hobby or a business. If you choose to do this as a business, though, then it's important that you have a realistic understanding of what it takes to succeed in business. I mean you no disrespect in saying that most of us here have more years on this earth than you. We have the benefit of more years of life experience, and we're trying to give you some of that benefit.
So, with all of that said, I'll give you a little of my background before offering some ideas: I owned my own law practice for several years before I had to close the doors. In retrospect, I know which mistakes I made, and which factors were beyond my control in the failure of my firm. That's the life experience that I bring to the table. I'm also what I'd call "mechanically reclined." IOW, crafts and mechanical things do not come naturally to me. I'm a "words and concepts" guy. I have to be really careful doing any sort of craft because, if I don't, I'll get impatient, hurry the job, and it will come out looking sloppy.
If you want to do this as a business (not a decision that you have to make right now, obviously), you'll need more than a dream. If you watch any reality programming, you'll constantly hear contestants say "X is my life. It's all I want to do. That's why I should win the bajillion dollar prize nand contract." That's not enough. You'll need marketable skills (like the woodworking). You'll need "ancillary skills," like accounting. Some of those skills you'll need for yourself, others can be hired. You'll need start-up money to pay bills (whatever you might have) and to buy supplies. You'll need a market for those skills. I might make the most fantastic SuperWidgets in the world, but if nobody wants a SuperWidget, Spats' SuperWidgets is doomed to failure. You'll need to consider legal issues, such as forming a corporation, in the event you need to take out a loan to buy a shop. By saying this, I do not mean to say or imply, in any way, that you should not do it. I loved working for myself. (It just turns out that I'm a very good lawyer, and a terrible businessman.) I'm just saying that there are many factors that should be taken into account. I would hope that you would take the advice here in the spirit in which it is offered: an attempt to help you succeed by getting off on the right foot.
As for a hobby, I'll join in with the folks here telling you that you should get out and refinish "wood." Got an old, beat-up chair? Refinish it. Take your time. Woodworking takes patience. (As an aside, my grandfather built a bunch of furniture in his lifetime. My grandmother used to get mad at him because he wouldn't let her buy furniture. If she liked a piece, he went home and built one just like it.) Head down to Home Depot and Lowe's. When someone buys wood there, the store will cut it for free, which leaves them with some scraps that they can't use. See if you can get them for free or cheap and practice on those. (For that matter, HD or L's might offer a free class that could help you improve your skills.) Does your school offer a shop class? Woodworking? No, you probably won't get to build a rifle stock in school, but it's a free chance to improve skills.
