Blacksmithing sounds very interesting to me. I wanted to take the courses last year but didn't like the program - too much theory and less practice. Unfortunately, I haven't found another courses in my region, so I'm gonna wait for another opportunity. But still, it sounds cool though I don't think you can make a lot of money from the start.
And I agree with the PP that joining the military services give you a lot of advantages these days, especially in navy services. However, I know plenty of ex-military guys who are involved in finance/business right now. Well, you can even check out link removed to get more info about that. It seems that people of any profession want to be the part of business someday in the US.
