Your question imposes a choice, either documenting memories and history, or, "art" (whatever that is). I think this may be an unhelpful division of pictures into only two possible categories. Probably it is more helpful to view all options being open, the dividing lines are blurred anyway. I find I make both those sorts of pictures and plenty of other types also.
The ability to review and edit your own work, including finding out the hard way that something didn't work and discarding the print, is part of the learning process. For many people this is a slow gradual process of learning visual language. First comes the learning of the crafts, camera craft and darkroom skills both needed to make the picture. The process of learning visual language, arrangement of the frame, is there a horizon? where? the arrangement of lines, tones, colors and textures, how to chose the camera position, the lens, the light, the arrangement of the subject and background, are for many people harder to learn and it may take a long time to acquire these skills, sometimes years. Many find it helpful to study the work of other photographers, visit galleries, collect prints, buy books, attend classes, make trips for picture projects. It can be the journey of a lifetime. Some become very good at it.
