Dude, you're just saying that because he got a BA at 19. "Set up a goal and works toward it", that's not how it works, you gotta know what you really want first. I got a friend who's been co-oping since he's in college, he's the calculating, concentrating career type, that's because he know what he wants. He's in USA getting MA. prolly graduated now. Even a charging career type like him once confide in me "I might have picked the wrong profession. If I can do it all over again...."
Then I have another friend, graduated with a BA in math. He thought he got his career figured out when Quixtar hit him, "This is what I am going to do" and you can really see the Quixtar flame in his eyes. Now he doesn't mention Quixtar anymore. He's going nowhere because he isn't sure what he wants.
Then there's a friend of my dad's. He became a doctor as his parents wished. Now he's near 50 and he said he would rather do what he liked if he were wise enough to defy the parents and choose what he wanted.
Unless you already know what you want in life already, there will be EXPLORING. Not everybody moves out alone to a big city at 16 and became a rock star.
