As long as you have good lines/features in your face (not a crooked nose etc), great hair, decent muscularity (not scrawny or fat) and is not too stupid or retarded you can go places.
The keyword is to be (or try to be) above average in every aspect, be it arms/biceps, back, knowledge of useful things, social skills, how to make money, how to treat people) etc
Features can be hard to change so some visit the plastic surgeon (fix eyes, nose, lips, chin etc) but you can always improve your features as much as you can by dieting down so your lines are shown and not covered by fat.
Hair is another aspect that can be improved if it's an area you lack in that can change how you are perceived.
Being above average in many if not all aspects helps a lot, but if you cannot be, let's say you are bald, you can always excel (be very good and not just mere above average) in another aspect/area, like intelligence, sense of humor, physique, charm, making money etc
If you have a Kai Greene-nose that ails you, just fix it.
