i kind of observed the people to whom i've once developed a personal interest. i tried to find their similarity, and i came to one word: intelligence. i either have seen them as someone with deep thoughts, broad knowledge, good diction and writings, critical thoughts, witty jokes, and many other things like that. they all have it in them, and i tend to admire guys whose attitude or action implies (and yes, i use the word 'imply' not, like, a direct 'show') their awesome intelligence. so, yes to this word.
