It is not just having thoughts that makes a good thinker, conversationalist and blogger but the ability to seize them and verbalise them. That much is obvious.
Similarly it is not simply having inspiration that makes an effective artist but his or her ability to commit that inspiration to a preferred creative medium with assurance and skill.
My father is of the opinion that unlike the political game, where one needs to be shallow and single minded, art allows for deeper, more divided natures to express themselves.
I still think, however, that being unified in one's consciousness and being intellectually, emotionally and actively congruent is more conducive to successful creative industry than productions born of internal psychological division.
