What exactly do I do when it comes to photography?

It is very difficult to define it - even to myself....

I do keep coming back to the light ..

drawing with light...
The word "photography" was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), "light"[2] and γραφή (graphé) "representation by means of lines" or "drawing",[3] together meaning "drawing with light".[4]"
