It's pretty straightforward to motivate people. You just have to make that what you teach them has value that they can use immediately. For example, to motivate someone to train in self-defence, just beat them up every week. Now learning self-defence will have value in their life. If they don't get beat up weekly, what's the point of learning self-defence? If it's only once a year, then who cares. Spending time every day to counter something that only happens once a year isn't worth it. It's less trouble to get beat up once a year than it is to spend learning self-defence daily. There just has to be an immediate value in what you teach. If there isn't, there's no point in teaching it. Students will just forget it anyway after the test.
