As with any art, be it photography, painting, music, writing, etc., a craft must be mastered. Without mastery of craft, any art becomes a hit or miss (mostly miss) struggle. Even with craft under one’s belt, creativity is not assured. Even the degree to which a craft is mastered depends upon intelligence, level of persistence, time and thought devoted to practice and mental concentration.
The difficulty with photography is that hat need for craft is not obvious. Making music on violin or banjo, for example, requires achievement in a craft. The need for craft in photography is hidden by “you only need to click the shutter, we do the rest.”
Doing photography without learning the craft will always remain a haphazard struggle. Not every picture taken by a master is a success. Photography, just as with any art, can be very humbling. There are no short cuts!
David Vestal’s book title said it all, The Craft of Photography. Also Feininger’s Total Picture Control.
