People cannot give what they do not have. Young people are dealing with a lot of challenges; hormonal change, peer pressure, socio-economic challenges, parental pressure and the list goes on and on. We could have a private chat. I suggest you first try to understand who they are, their background, why they are nonchalant, show that you care. I believe that there must be some among them that you can speak with, that can tell you what some of the issues are. You must show that you care about them, more than the project, after all, they are the people you want to empower, make them partners, instead of beneficiaries. I have worked with young people for more than two decades. You must believe in them and make them realize that they can become more.
Some of them have both victim and entitlement mentality that stems from their background and societal construct.
