Help with motivating a teenager

[Irulan]

Being a stay at home mom, I do everything around here and don't really require much from him other than good grades and he's not doing that, so my thinking is he needs some responsibilities.
Anyway, ask any questions and give any advice.
I can choose to agree or not, but I need input.
Thanks in advance.

more unasked for commentary.
14 is plenty old enough to do lots and have lots of responsibility. The Boy Scout motto, "never do for a boy what he can do for himself" is really important. This is kind of getting off the giftedness thing - But I feel strongly that given a kid, yes even a 14 year old, responsibilities and the opportunity to both fail and succeed is critical to the development of a balanced man.

What about a program where he's got a chance to develop some leadership skills? Some scout troops are still focused on leadership by boys (not the moms and dads) and this can be a great opportunity. Or, volunteering (in something he's interested in).

And, helping around the house. Laundry, cooking housework, for starters. People thought I was an evil mother because I quit doing the kids laundry when each was 12. It's not rocket science.
