you only need to be smarter than the average bear.Thereafter, different skills are more valuable.
I agree completely with this.
There are a few roles (not professions per se) where you need serious intellectual muscle - ironically these tend to be not that great paying, I'm thinking of fields medal winners, astrophysicists etc.
But most 'professions' (medicine, law, science, engineering) do not require genius level intellect. They require you to be smart enough but then other skills dictate how well you do. And those skills often come down to persistence, doggedness, resilience and reliability. Along with being able to work with other humans (whether you enjoy it or not.) you don't need to be an extrovert party animal to be a good people person. Apparently I'm good at it despite (or possible even because) I'm introverted and don't need people.
Medics are generalists, and again, you need to be smart enough, but you don't need to be a genius. You need good information retention/recall and you need a certain set of skills and personality traits - calmness, doggedness, stamina, ability to deal with people who are often frightened and in pain (the classic bedside manner.)
