I don't know, I just don't feel like doing anything.How can you change apathetic behavior?
that is one of the huge problems: you can't make someone care. it is extremely difficult to make someone care about something they don't care about, because we as human beings spend so much of our time, effort, and energy convincing ourselves that we are right in our choices of what we care about and don't care about. we get social support from other people to back us up, and ignore evidence that will compel us to change or look bad.

that being said, i suggest doing some extreme activities. not as in, extreme sports that could kill you, but just get the apathetic person to do things that they have never done before, and probably never will, simply to expose them to what is out there to care about. get them to try new things, since they don't seem to care about what they've seen of the world already. see new things, meet new people, do new activities, just expose the person to as much of what life has to offer and as much of possible things they could care about.
