Surely almost all of us have been through that stage at some point, right? As a kid, if you told me to take a picture of something specific, I could meter and set the camera (all manual!) and focus and get a technically competent photo, but I didn't know thing one about composition or intelligent use of lighting. I may now be a little bit past that, but my technical "how to use the tool" abilities are still far in excess of my artistic ones, and probably always will be.
I envy the exceptions, the people who come to photography with a really strong, developed sense of what makes a strong image, for whom the hard part is just learning how to control a tool to match their vision. But maybe that's a "grass is always greener" thing and they envy me too for the opposite reasons.
