I just saw a big-name photographer, who should know better, repeat that awful platitude, "It's all about the light."
Ugh. No. It's not "all about the light." What a creatively hollow hobby or profession photography would be if it was.
Photography is also about anything and everything you choose to make it about. In addition to light, it's about lines and shapes and colors and textures. It's about making records of significant events and conveying information. It's about emotions, ideas, content, memories, meaning, communication, storytelling, and a million other things.
And don't give me that blather about how because "photography" means "writing with light," it really is all about the light. That doesn't make it any more "all about the light" than novel writing is "all about the ink."
If you want your pictures to be only momentarily interesting, then instantly forgettable, then go ahead and make them "all about the light." If you want to make pictures that engage people's minds and hearts, then perhaps aim a little higher and put a little more into your photos than nice light.
