When you want sound legal advice, you ask a lawyer. When you want sound medical advice, you ask a doctor. When you want your particular question answered, have you asked a PROFESSIONAL carpenter? (Just a rhetorical question; no need to answer it for me.)
Where I live, there is a trade school. As I mentioned, you can ask a professional carpenter what to do, or you can go to a VoTech and ask a teacher who teaches basics on where you can go or what you should do. That's all I can say unless you can find someone willing to train you. My $.02 is to get some formal schooling first. This will put you much higher up on the pay scale in your first job because you're not starting cold. Also, there are a lot of aspects to being a carpenter. There are Finish Carpenters and 'Builders'. There are others but I'm not going to tell you because that's Lesson #1 and it's for you to find out. They're all fun to do.
