Take him out. Be a role model. It doesn't seem like he likes sports, so take him fishing. Or throw a frisbee with him. Teach him skills that he can use to his advantage, like meeting new people, and shaking people's hands. And building things. Take him to a maker faire/shop. There he can meet other people (such as STEM students). There, with the people he met, he can subconsciously pick their brain, and grow some motivation to do something different with his life.
If he doesn't like that shit, take him to a music concert. If he doesn't like music, change the genre. Try taking him to a contemporary dance concert. A ballet recital, even.
If he doesn't like any of that, take him to a car show/meet.
If he doesn't like any of the above, try building something with him. Like a deck or a doghouse if you have dog(s). I loved renovating the house and painting the walls with my dad.
