I'd put persistence top. Talent may get you noticed at first, but persistence keeps you going. You need persistence to write a novel full stop, and doubly so when you have a full time job doing something else. And then persistence to keep going when you have set backs.
But dogged persistence isn't enough when you're banging your head against a brick wall. You need to have the ability to adapt as well. Perhaps there's another way round that wall, a different route that could be taken. An adaptable person will try many ways to achieve their ends.
Along with persistence and adaptability, I'd cite willingness to learn. From classes, from reading, from other writers, from feedback - it doesn't matter where the information is coming from, but a writer needs to be open to all learning opportunities.
But not necessarily to take on board every scrap of feedback, because a writer also needs to have self-belief and the confidence to reject feedback if they think it is wrong. Self-belief and confidence also provide the fuel for persistence and openness.
So, can you teach talent? No more than you can teach persistence, or adaptability, or openness, or confidence. But surely these qualities are innate in all of us. If we're lucky our childhoods will have equipped us with these qualities. If we're unlucky then we have to do what we can to develop what we've got. Can you teach these qualities? No. Can you nurture them? Yes.
Discover the best ways that nurture your writing qualities - it might be a support group, it might be a writing class, it might be uninterrupted writing time away from home, it might be all (or none) of them. Discover what works for you. And then do it.
