As an alternative to sailing away and escaping from the unbearable world that forces you into a life you don't like: you can persist and change your environment but it takes effort. I think most apathetic people would be interested in something but their lack of knowledge hides these things from them or renders these choices as unreachable. Being apathetic is a down-spiral, If you are not interested anything, in any of the paths you think are available for you then your life becomes a burden in which you are just executing tasks you are expected to execute. The amount of your daily joy becomes zero or less. There is no amount of physical activity or shitty mediocre advice can help with this. An apathetic person has to find a dream that can be pursued, or he/she has to realize that one of his/her unreachable dreams is actually reachable. It takes a single day to turn into excited from apathetic.
