: Yay for both of you!
I've got a 14yo and a 17 yo, both are homeschooled. (Also 3 youngers, but that's just background). The 14yo is finishing up her freshman year, and the 17 year old is finishing her Junior year and thinking about graduating a semester early.
What's worked for us: AMEN on the sleeping in. Let him sleep! I also saw a world of good changes in my 17 yo when she started truly taking her daily vitamin, plus cal-mag and a sublingual B-12. They're so busy they just burn everything up!
We do a lot of volunteering. My girls helped start a teen library group that has turned into a huge success, they volunteer all summer for the library's summer reading program, they usually go to Conservation Camp in the summer, and they're both very involved in our local Youth Court (in fact, they're doing their volunteer work w/ the youth court as what is called "Service Learning," and each girl is earning one credit this year for the time she's put in with YC).
It's really important to remember he'll probably be able to get done in one hour what it would take a week to do in school classes, so watch out for the, "This is NOT a full school day, young man!" syndrome. I had to stop myself doing that with my girls several times.
If there's something he's really into right now, like ornithology, or botany, or health care, usually there is a volunteer program somewhere (try Universities, hospitals, your local VFD, etc). Also he can take university level courses in many places if that interests him.
Good luck, and give it time!
