So we know that emotions are contagious—and while your partner isn’t the only factor, depressive thinking definitely plays a role in whether your connection leads you into despair or helps you stand strong as a support system.
Being surrounded by apathy acts in a similar way, except if you are committed, in which case it can bolster your cause. This is where you should focus on if those around you are floundering, yourself and try to find like minded people where you can. Is this not what happened in this film anyway, did he have the same view on life at the end of the film ?, as he went through his character arc/inner journey and came out the other side renewed.We interpret the actions of the people around us. When we see people acting indifferently to a task, we know that they are expressing a lack of interest in that task. That lack of interest is then related to our existing commitment to a goal. When we are wavering in our commitment to a goal, then seeing others who are apathetic nudges us in the direction of giving up. When we are highly committed to a goal, then seeing others who are apathetic actually increases our commitment.
