Here's an observation by author Aldous Huxley ("Doors of Perception" ,"Brave New World") regarding the paradox of creativity: reconciling the discipline of doing the work with the necessity of allowing room for the artistic and intuitive subconscious to kick in:
Take the piano teacher...he always says, Relax, relax. But how can you relax while your fingers are rushing over the keys? Yet they have to relax. The singing teacher and the golf pro say exactly the same thing. And in the realm of spiritual exercises we find that the person who teaches mental prayer does too. We have somehow to combine relaxation with activity… The personal conscious self being a kind of small island in the midst of an enormous area of consciousness... What has to be relaxed is the personal self, the self that tries too hard, that thinks it knows what is what, that uses language. This has to be relaxed in order that the multiple powers at work within the deeper and wider self may come through and function as they should. In all psychophysical skills we have this curious fact of the law of reversed effort: the harder we try, the worse we do the thing.
