My Sim has almost reached level 10 of the stylist career, but then I think she's going to quit. Working 5 days a week of the same thing gets old and too much like real life! She's only 50% done with her portfolio at level 9, and it's a real grind. Even though all of her clients have been happy except one or two, whenever she gets the wish to give fashion advice, it almost always goes over very badly, and the client ends up dropping from a good friend or friend to merely an acquaintance. This is with a Sim with has all of the charisma skill challenges and charisma related lifetime rewards (long distance friend, etc.) completed, too.
