I'm not making an argument for pick up artists or Jordan Peterson per se, just the notion that it should be possible, if you so desire, to change. To break free of bad habits or inculcate good habits. To make better decisions. To take better care of yourself. To do more of the things you have identified as being good for you and fewer of the things you deem bad for you. To identify the forces which are preventing you from taking the actions you wish to take, and defeating them, in violent hand to hand combat.
