If you don't use the energy you have been given by nature to build yourself and go after your desires - then that same energy will start working against you. Self sabotage, emotional outbursts, stress eating, emotional reactivity, impulsiveness, being bitter & envious, feeling of hopelesness - they all wreck you bit by bit. Then you are going to wonder if there's something wrong with you. And then it becomes your identity. You become meme'd into believing this is how you are born. Always remember, unused energy doesn't vanish in thin air, but when there's no healthy outlet, it will turn your body and mind against your own self.
