as salam alaikum
a better translation for "nafs" (which is often translated as "soul") is "self" which is in fact your true self, what control your body and the real addressee of Allah's Speech. Your self can command to evil: "Surely the self is prone to enjoy evil" (12:53). It can reproach himself: "No! I swear by the self-reproaching self!" (75:2). It can also be at peace and his Lord will call him by saying: "O you self at peace! Come back to your Lord well-pleasing and well-pleased..." (89:27-28).
With prayers for your success.
