I've always written. It's where I excelled, and I enjoyed it. I mean...my early writing is trash, but that's true of 99.999999% of mere mortals who take on a new pursuit, because you have to start somewhere, right?
And I still write trash. All the time. It's a better class of trash than it used to be, but you never stop writing garbage. Photographers take hundreds of photos and might pluck one golden image out of the lot. Fine artists draw and paint a lot of studies and sketches they'd never show anyone, in and around their finished works.
I think some people find different aspects of the creative process easier than others, and it can come more naturally for some, but I get uncomfortable with phrases like 'can creativity be taught,' because a lot of what people call 'creativity' is actually just 'work.' Like...the head down, butt-in-chair, wringing-blood-from-a-stone, frustrating, self-doubting, out-of-love-with-everything slog that you can't even objectively evaluate for yourself because all you know is that you're not satisfied with it and it isn't singing for you.
Muses aren't real. If you only ever produce work on days when you're feeling inspired, you won't get very far.
That is the scenic route to get to what I want to say, which is that I think anybody can get into anything. The limiting factor is how much of the work they're willing to do. Somebody for whom writing comes naturally can be paralyzed by their own dissatisfaction with their work, and never finish anything; their neighbor might struggle to put one word after another, but invest enough butt-in-chair time to be published first. Prolific, even. They say 90% of writing is editing, anyway, but if you never get the first draft down, it doesn't matter.
And as @GreenFlashlight said above (and other people probably said elsewhere in the thread), getting the work down means being able to accept failure. Which is, in turn, partly because there are more Slog Work days than inspired ones.
As an RP-related side note, I don't think much anymore about how RP helps or hinders my writing. I try not to think about RP at all when I write outside of it. What matters infinitely more than that is what I'm reading. If I'm not reading, and I mean reading widely, outside of specific genres and voices, my writing gets cramped. My language stagnates. I don't have ideas, because I'm not putting fresh, diverse thoughts into my head and letting them roll around in there and bump into each other in unexpected ways.
