If I may add to the wonderful suggestions listed here. Give guidance - of course, but then let him go. Get "into" whatever it is that he is "into". Especially if you don't like it (and, it's not like mistreating puppies or some such). I love my parents, and they did the best job they could raising me, but there were some aspects of my childhood that I wish they were more actively involved with.

Mind you - I'm not blaming them - on the contrary I'm fully aware that every step I've made lead me to the point I am at in life and only I am responsible for my position.
