Fundamentals are essential, to a point.
The fundamentals are the foundation rules. They are recognized by generations of use, of mastery, of experts in the field saying “well, if you have to start somewhere, you might as well start with this.”
Fundamentals are essential, until they aren’t.
In some cases you can get by the rest of your life, doing whatever it is you do, just on the fundamentals of things. Assuming those fundamentals couldn’t be programmed into a robot or a bit of software and render you obsolete (turns out, not difficult to do at all). Mastering the fundamentals usually means minimum competency.
Fundamentals aren’t the point. What you do after them is what we’re all waiting to see.
Writing - good writing - is impossible to teach.
You can learn it, but teaching writing any further than the fundamentals is impossible.
Most people learn to speak, read, and write a language. That gets most of us from grade school to the grave. Writing classes in most schools are heavily structured with a tight framework - too many students, too few teachers, and how to assess writing on a standardized test? I think this ruins a lot of writing potential.
Every writer has the chance to shine on a new platform. Most of them don’t, because, well, rules.
Fundamentals are essential, until they get in the way.
There is only so much formal education can teach about writing and language. There is the type of Spanish you learn in a tenth-grade classroom, then there is the Spanish you learn living in Spain for a year.
There is the language curriculum teach, and then there is the language most of us use.
Rules homogenize most of what is published so it is accessible to the greatest amount of people. Eventually, the rules need to be broken and the fundamentals need to be tested.
Break the rules with intention. Know what rules you are breaking, why you need to break them, and the impact the broken rule will have on the audience.
Good writing is learned through the deconstruction of rules. Good writing happens when formal education ends.
