if you don't exercise (yet are capable), so much of your energy goes to your mind due to the separation between you and your body. lack of movement is responsible for the overthinking, overprocessing, addictions to social media, overfunctioning, sex without a heart connection, and obsessive shopping and consumption of booze and the like. your body is a nuclear powerhouse, the portal that nourishes souls from heaven to earth. if that powerful energy you innately possess in your body is not channeled, it will almost always lead to something destructive.
The kindest thing literature does is remind you that your peculiar little feelings have always existed. Someone, in some century, was equally confused by love, bored by society, tired of performing, and hungry for meaning.
