Why must I work ?

Why must I work in the future? I don't know. I don't work. I don't have the reason why I must do my best. I want the reason why should I work ? I have some question. What will happen when I don't work. I think that if I work I can get freiend. That is good, but I hadn't friends in my life, so if I don't have friends, I don't feel bad. I want the reason why having a friends is good? I have some question of my future,,,,. I think that I want to be poor man. Why do you work? for your family? for earn your money? Please tell me.
