Ansel Adams could be every bit as good with words as with images.
Too many people merely do what they are told to do. The greatest satisfaction derives from the realization of your individual potential, perceiving something in your own way and expressing it through adequate understanding of your tools. Take advantage of everything; be dominated by nothing except your convictions. Do not lose sight of the essential importance of craft; every worthwhile human endeavor depends on the highest levels of concentration and mastery of basic tools.
