In terms of writing, I could not have said this better. I love the truth behind this quote so much. This is amazing writing and grammar advice. I used to think that the rules didn't apply at all - that a lot of writing came from just doing your own thing. And while that is true, the only way you can break the rules as a writer is to know what to break in the first place. Something I will always remember learning, back then and now daily.
Break writing and grammar and story rules.
Break them often.
Breaking them is how brilliance is crafted.
But know what you're breaking - why and how.
