From m-w.com:

Main Entry: skep·ti·cism
Pronunciation: 'skep-t&-"si-z&m
Function: noun
Date: 1646
1 : an attitude of doubt or a disposition to incredulity either in general or toward a particular object
2 a : the doctrine that true knowledge or knowledge in a particular area is uncertain b : the method of suspended judgment, systematic doubt, or criticism characteristic of skeptics
3 : doubt concerning basic religious principles (as immortality, providence, and revelation)

Considering the dictionary definitions, it doesn't appear to me that skepticism is the sort of attitude that allows creativity to function. Creativity, it seems to me, requires faith and belief in the ability to create, not skepticism about the ability to create.
