Everypony has their own special, personal, unique talent. Just because some are more obvious or may seem more impressive doesn't mean there is nothing about you or anypony else that isn't amazing and special.

[Humans may have a much harder time of it, she muses, without cutie marks. Cutie marks do so much to help ponies understand what makes them unique and special. Humans, on the other hand, seem to often struggle with that knowledge, or even forget it entirely.]
