people called "Scanners"
Possibly related to plurality: Has anybody heard of Scanners (in terms of people)?
A Scanner is "someone fascinated by so many areas she can't settle for only one."
I'm not a big fan of labelling here, but it actually helped a lot of people. Barbara Sher coined the term and wrote a fair bit on it.
"To Scanners the world is like a big candy store full of fascinating opportunities, and all they want is to reach out and stuff their pockets."
"It sounds wonderful, doesn't it? The problem is, Scanners are starving in the candy store. They believe they're allowed to pursue only one path. But they want them all. If they force themselves to make a choice, they are forever discontented. But usually Scanners don't choose anything at all. And they don't feel good about it."
