My real take on this is just let the kid do whatever, and eventually he's going to figure it out for himself. I think a lot of you are forgetting what it was like to be 18. Yeah, he's an idiot. We all were. Of course he thinks his dad doesn't know crap about any of this. I thought I knew everything when I was in college too. And my father's advice, as solid as it may have been, wasn't going to stop me from drinking/smoking weed and dropping out of school. It just made me resent him, because I felt I couldn't talk to him about anything without him making me feel bad about myself.Any mistakes he makes here aren't going to be unrecoverable, so just be there to give him support when this whole thing turns out as you are predicting, and he'll learn a lesson from it. Sounds like there's about a 0% chance that this is going to work out the way he's dreaming, but who gives a crap. He'll fail and hopefully he has some pride, will learn something from it, and eventually it will propel him to greater heights. This is the same thing I'm trying to impress upon my wife right now, who lords over the kids and doesn't want them to make mistakes, get injured, etc. No matter how many times your parents told you something, you always knew more than they did, and the only way you were going to learn otherwise was to fail and improve on that. Just let him fail.
