Interesting post! Having talent helps: some people are better at some things than others. It's nearly impossible to keep practicing when you're bad at something and the improvement is in tiny increments, because the goal is ridiculously far away. Being even a little better than average makes easier to imagine success: I could never have been a good basketball player, though I could have been a much better one had I tried.

And the more you love something, the easier it is to keep practicing, mindfully. I liked folk dancing and kept on with it, despite my general lack of coordination. My girlchild keeps on with dance classes and is practicing recorder (because her cast won't let her play her flute). She's got some talent for both and they make her happy. It's a positive feedback loop.

So, I guess playing and writing are not so different from any other kind of craft. (I don't know what makes something ART, though it clearly involves culture and presentation as much as anything.)

You have the talent and the pleasure in writing, I am sure that your practice will help with the craft.
