Son, your turning 19 and all you is a doing is telling us what you want to do? Get your butt out there and go spend some money getting what you want B-day boy. How the hell ya gonna be able to experience what most of the population is going through right now, if you don't start out spending beyond your means?
Seriously, SS I know you want suggestions because in some strange way you believe we all have experienced everything and advice should come easy, but I can remember being 19, strange enough, and I know that opened the door of freedom and choice for me and I pretty much did what I damn well pleased from that point on, even with suggestions from more experienced people. That's how most of us learned and sometimes we wished we had taken the advice offered. Go do what you really want,
make good decisions and enjoy the still youthful part of your life. You seem to be more mature now mentally, than any 19 year old I have ever met. Happy Birthday son.
