well, i would assert that it's a practice, not an inborn talent.
Take me for example, I spent nearly my entire life as a visual artist/photographer/designer.....I always wrote down ideas and impressions, but I couldn't write very well to express my ideas. Then there was my drinking which really impaired my thinking......I couldn't write hardly at all. It wasn't until i went broke and applied to like 200 jobs, and was hired as a writer that i discovered that I could write ok, if i practiced like 10 hours per day. The only reason i got that first writing job was because i was desperate, not because i thought of myself as a writer.
Then i got several more writing jobs, so i practiced writing for like 10 hours per day every day. No days off. I did this for about a year. Now it's a habit. But I have to push myself to write challenging things still. The practice will never be over.
