I'm glad I'm not the only one who gets this way!
I've always been a huge bookworm- often even re-reading the same old book in multiple languages just to see what came across differently in translation- but when I started creating my own content, I found myself actually dropping books and movies midway because I was struck by an idea or sudden motivation to write. The first few times this happened, I actually felt a strange sort of shame for not finishing something- but now I've come to accept it as part of my creative process.
One thing I do worry about sometimes is how an author or artist I admire can impact the direction of my work. I'll get carried away with how they explore a certain theme in their writing, or find an art style radically different from my own to be seductively beautiful, to the point of wanting to incorporate elements of it into my own drawings. Of course I can see the potential advantages of this habit. It ensures that I keep developing as a creator in a multitude of diverse ways. But on the other hand, it also makes it very tempting to go back and rework things indefinitely- or makes me worry that my "brand" as an artist is not consistent enough to always be recognizably mine.
With that in mind, I feel like reading and watching stuff that inspires you is great- but only to a point. There's something to isolating yourself to outside influence every now and then to figure out what your own unique creative voice sounds like.
