that depends on the direction you are choosing for youself.
fightings helps you in gang activies. when you try to kidnapp someone else's girls or offer them a job & in cockfights.
seduction : helps you pleasing cougars better, so they will come back & pay you more money.
sweet talking : when u get contact to girls & you take them out, with better sweet talking points you have more chance to make them fuck buddies. also when u go to pub & meet them you have better skills to get their contact.
intelligence : as a pimp clients pay you more, & classes in pimp school take less energy or excitment.
artistic vission : u write better scripts, make better movies & take better photos.
also intelligence & artistic vission are necessary for finishing school bussines lessons.
my advice to you : dont spend all of your points in one factor. u need all of them more or less. but with low sweet talking u cant get girls with high sex appeal that means less money for your parlors your hoes & ... this one is really important but u need them all.
