my mom pointed me towards fiber art because I like to stim...alot and fiber art is alot like stiming while making something. Alot of repititon. Also she pushed me towards being an art therapist when I showed alot of interest in art. Mostly she just let me try it for a day or two and research it.
but as Pensieve says, you need to talk with him about the facts of life. I suggest getting the statistics of the job market, showing him your budget for what it costs to pay bills. Have him help you pay bills and talk with him about the budget so it is not this thing that he sees is so far away, but something that he needs to be raised to understand. I disagree with how my parrents raised me when it comes to money. they just did it all for me and then one day, I am supposed to figure it out. You need to make living independantly more real for him. I also suggest that you use his Xbox as his reward for doing the things he needs to do. Like in the working world, work comes before play.
good luck,
Jojo
