K.S.
I was really lost at that age and did not enjoy school. What turned me around and might be interesting for him is archaeology. I fell into it as a volunteer on several expeditions when I was still a teenager and it shaped my career path for the future. There are a lot of historical and archaeological societies that use volunteers on digs. It is a very cool thing to do for people that age and it does get you outside in the open air and uses both muscle and brain power. And this is something you can do with him. Most digs will require a parent to accompany if the person is under 18. There are also week, two-week or month-long expeditions you can go on as a volunteer. You just pay your own way and work for free but the experience is invaluable and archaeologists are usually very neat and interesting people (if I do say so myself) and provide great role models. Try your local city or county-run archaeological program first (most municipalities will at least have one archaeologist on staff--sometimes in the urban planning office) and they can point you in the right direction. This is especially timely with the new Indiana Jones movie coming out in the summer. He can also learn about a profession that is pretty neat and has many different angles--math, science, art history, anthropology, geology, chemistry--all of these factor into archaeological research. And he may just find a career track that would interest him.
