Read a challenging book
This one is for those teens who like to read (you'll only make non-readers hate reading even more if this is forced upon them). Help pick out a book that's above their reading level but still doable. Choose a genre that they'd not necessarily opt for usually, or pick a classic that they might not have heard of before. There's plenty of classical literature with social themes that resonate just as strongly today as when the book was written.
