It is often said by most published authors, if you want to be a writer, read. Not just the genre you are writing in, but everything you possibly can. This logic can be applied to anything. If you want to be a designer, collect and observe design. If you want to be a filmmaker, watch movies. If you want to be a musician, listen to music.
However, this reasoning falls apart when your consumption outweighs your production.
If you want to be something, you need to do it. Yes, you need to understand the language of the medium you are working in, but too much consumption can lead to doubt.
It’s okay to be shaped by what you consume, but consider the act of creation akin to exercise. Without it, you will grow fat and lazy on the ideas of others.
