a "bootcamp"!! :lol:
Seriously...it's going to be HARD (I've BTDT with my 3) but you basically need to come up with a list of expectations, talk about them with him, (give him a copy if necessary) and then follow him as he completes the jobs -- correcting if necessary and all he's allowed to say is, "Yes" or "No". NO ARGUING... if there is ANY resistance, etc., he starts losing priveleges. (mp3, TV, computer time...anything that he enjoys) and he has to EARN it back.
It might take a week or so, but I think you'll be pleased with the results.
