“Fairy tales are more than true: not because they tell us that dragons exist, but because they tell us dragons can be beaten.” -Neal Gaiman
I agree with this quote. I think that this translates to the idea that if all their young life, children are told that they are fully capable of slaying a dragon, then when they grow up, that confidence will transpire. It teaches them they are capable of achieving their goals and really should reach for the stars. The prince wants the princess, so he slays the dragon in order to save her. And he can always do it. Everytime, if that prince wants something he goes out and gets it for himself. In the process, doing whatever is necessary. It teaches kids that if they persevere, and really try, they will reach their goals. It teaches them that even if that dragon looks really big, and seems impossible to slay, they have to try.
