Photography (or any art form) is all about achieving your own personal style.
Nothing more true than that. In my Photoshop class I see every year people trying to imitate the style they see on the ads. It's a great shock for them when later in the year they realize that ironed images and flawless smooth skin is not art on itself. From that point on they sort of "reboot" themselves to a new brain. Then they start to "destroy" and reconstruct their images to something new, until they realize that other people have done this and even better. Then they "reboot" to a new version of themselfs and so goes the circle on and on until they "mature" but several years after they have finished the class.
