It's tough. When I was a teenager, I probably would have abandoned school had my mum not done my homework with me when I missed school once for 10 days because of external reasons.

The truth is that at that age, you have a very short-sighted perspective. What your son wants to do now is gf and chill, which he will most likely regret when he gets older. It would be very hard to explain him that for sure...

The use of discipline is good, but it shouldn't be pushed to the point where he just runs away because his life is just awful.

If I was in your son's situation, I would want some sort of partnership to be established. If I do my homework, I'd want my phone back for an hour or two, for example.

The other solution is developing a sense of responsibilities. He is not responsible now, and so the idea would be to give him responsibilities that would have a big impact if he didn't attend to them.

That's about all advice I can give. All kids are different.

Good luck.
