What is the most important concept in photography?

The first step, I think it should be interest. As long as you like and love photography, then you have taken the first step into the field of photography. Interest is the best teacher. As long as you have a strong interest in one thing, you will try your best to make it successful. With a little progress, you will feel more like a photography genius and have a sense of accomplishment! Then, under the guidance of interest, solid technology, unique creative inspiration, broad thinking space, keen insight and so on will be gradually recognized, mastered and fully exerted!
