Hmm do you live that out then? If I did, he would watch YouTube and play computer games, poison the dog with chocolate, leave his trash and clothes lying around everywhere, and never go to school again. Oh, and of course he wouldn’t go to bed, never brush his teeth, and he probably would never reach the age when one usually starts their vocational training. I dare say it would be similar with your child. Regarding his career choice, he would try to become an influencer, pursue nothing else, and probably make a living with Hartz IV and/or occasional jobs. Although, I am wrong about him: at the moment he shows interest in the volunteer fire department. Maybe he wants to become a professional firefighter. I would find that great, too. Replace "muss" with "should, if you want financial security and an interesting job content..."
