Define cool and then make the list.
Amazing musicians who seem to be blessed with a natural affinity? People with an infectious charisma who entertain and charm with such joy?
Or, as is often the definition of cool, people who are so hardened inside that they literally do not care - about other’s opinions of them, about social norms, etc. - as much as others? Caring less does often equal cool. And it’s not necessarily a good thing. The Fonzie character at first was this kind of cool. No skills, no talent or charisma. Just hard enough not to care, which weaker people sometimes gravitate towards.
Personally, all my life I had an aversion to “cool.” Not that I gravitated towards its opposite (geekdom, or whatever) at all, either. Not in the least. It’s just that I always observed that those who seemed to most value “coolness” were invariably the most vapid people around.
Always sought out individuality and strength of character. Even when I was actually quite young.
