Like all things considered lucky I think having the “cool girl” as your partner requires preparation and an at least marginally directed willfullness to meet her. Either your upbringing preps you, you do it yourself or both.Even if you are wired in favor of committed relationships, you can not meet the “right” person if you can not be the “right” person and also protect your independence and faculties to chose until the right one comes along. The right one would be someone with mutuality of skills, will and conviction ..and be at least… what was it… at least 40% or at least 60% hot? It helps to have a couple of interests in common.
