You say you're 17 ... I assume you're still in high school, does your school offer any welding shop classes???? Ag shop??? Or do you have a Junior College close by that offers welding 101?? Even if you're still in school, many JC's will still allow you to take certain classes, and many are offered at night. I would strongly suggest you take advantage of something like this, it'll save you a lot of time and money in the end, and by the time you finish, you may even be able to answer your own question. Or maybe you'll find out you don't like it after all, all you'll be out is the cost of the hood and gloves ....
