My sons 18 and just finished his first semester at college, he seems laser focused on what he wants to do. So i wont use him as an example, but me at that age i was floundering, i quit 4 year college was not ready for it, Started working full time as a technician in the engineering field but found my way. Ended up finishing my college education at night while working full time and raising a family. Took me 12 years wouldn't recommend it to anyone but its what worked for me. I'm not too sure if my parents could actually steer me any differently at that age. As Berg said and Mykk said you've probably done all you can at this point. Be supportive... Ill have to check with my older brother i think he laid claim to all the old D&D paraphernalia when we cleaned our parents house out.
