I'd say "social skills" is not a homogenous set, but a combination of various skills, some of them more or less used in different contexts; depending on with whom you communicate (LW members? educated person? friend? average person? child? teenager? adult?) and how you communicate (in person? in writing? one to one? in a group? at a goal-oriented task? at a social event?).

Maybe you should update more about some of these contexts than about others. Split the "social skills" into individual skills, and evaluate each one separately. Recall specific situations where you have recently succeeded or failed.
