I have not had this problem at all with our daughter. She is now 25 yo. First off you must not spoil him and if you have then you have to start unspoiling him!

He is coming up to the age of developing a work ethic. If you give him everything he wants then there is no incentive to work. 14 yo is still young but he should be doing a paper route. 15 he could be working part time and certainly working summer months if working during school would jeopardize his marks. Eventually he is going to need a new computer or software. This is your opportunity to tell him to pay for it with a part time job.

How do I know about this? We have a neighbor's "boy" of 29 who has never left home and works occasionally. He spends most of the time on the computer(x box!).
He is grossly overweight. The father died a couple of years ago of a heart attack.
The mother now has a new boyfriend moving in and the son feels threatened.

Anyway this is an aside but you can see what happens if the child is overindulged by the parents. Work ethic is key and it starts early. Hope this helps!
