. . . with the exception of some specialists who have a passion for their field, very few people are as intensely interested in what they do as
Scanners. Also, almost no one has such a low tolerance for boredom as Scanners -- for them, boredom is excruciating. And, by definition, no one has as many different interests as Scanners. This makes their comings and going very noticeable to the eyes of others.
But the main reason Scanners are different from others, and the reason they get noticed for not sticking to anything, is because they learn faster than almost anybody.
The typical Scanner runs through her interests in record time because she has a big, hungry brain and her favorite food is learning. Scanners
love learning more than anything else. And learning is what they're most talented at.
