I'm going to echo grumpy old man Miyazaki for a minute because while I do think it's important to know the medium(s) you work and create in, you need other experiences to make things yours. Otherwise you will be mostly doing reproduction. There is nothing wrong with reproduction, it's a great way to learn, but if you want your own voice as a creative, you need to branch out beyond your medium.
I have most of my experience in writing and programming, though I hang around animators enough to have picked up some of the language. And what I am about to say is useful across all these different disciplines. Pay attention to the real world and what is around you (real here meaning things that are not fiction, the internet is real).
Art is abstraction and you can be much more deliberate with your abstraction if you have a sense for our reality and the people and things in it.
If you are writing dialogue, study how people speak in everyday conversation. If you are modeling character interaction, study how people act near each other, look at what people in different fields think about it. Limiting your references is limiting your creativity.
