Perhaps the most fundamental condition of creativity is that the source or locus of evaluative judgment is internal. The value of the product is, for the creative person, established not by the praise or criticism of others, but by himself. Have I created something satisfying to me? Does it express a part of me – my feeling or my thought, my pain or my ecstasy? These are the only questions which really matter to the creative person, or to any person who is being creative.
This does not mean that he is oblivious to, or unwilling to be aware of, the judgments of others. It is simply that the basis of evaluation lies within himself, in his own organismic reaction to and appraisal of his product. If to the person it has the “feel” of being “me in action,” of being an actualization of potentialities in himself which heretofore have not existed and are now emerging into existence, then it is satisfying and creative, and no outside evaluation can change that fundamental fact.
