Gnos is correct. I think intelligent adults can recognize characteristics they like in a wide variety of people and possibly try to develop them to an extent. Of course, they may have characteristics they may not like so they can ignore or reject them. Spock, S. Hawkings, George Carlin, Kathrine Hepburn, Leonardo da Vinci, Franz Schubert, are just a few of the famous people (or characters) I admire. There are a great many others who are not famous, but their names would be meaningless here.
There is a much larger reservoir of people and characters with behaviors I don’t care for. I’m not going to list them, but in a momentary glance at an above post, I misread it for a second and that brought to mind one of them; a character I enjoyed thoroughly, but who had a terrible or tragic flaw - Humbert Humbert.
