Just do what you want to get to where you want to be and always put yourself first without considering the needs of others. You don’t need to lack empathy to do this. I’m sure after a while of purposely thinking differently, you’ll naturally stop caring as much. Or you could damage your medial orbitofrontal cortex, right superior anterior temporal lobe, the subgenual cingulate cortex, and the anterior insular cortex regions of your brain. But I wouldn’t recommend the latter ha ha ha. Also you seem soft asl, don’t think this life is for you bud. Your best bet might be developing a friendship w a sociopath and have them do the dirty work for you. You don’t wanna end up living a life full of guilt & regret for your actions. I can’t imagine what that would be like lmaooooo literally
