Talent is extremely common. What is rare is the willingness to endure the life of the writer.
The real writer is one who really writes. Talent is an invention like phlogiston after the fact of fire. Work is its own cure. You have to like it better than being loved.
I don't teach writing. I teach patience. Toughness. Stubbornness. The willingness to fail. I teach the life. The odd thing is most of the things that stop an inexperienced writer are so far from the truth as to be nearly beside the point. When you feel glosbal doubt about your talent, that is your talent. People who have no talent don't have any doubt.
A little talent is a good thing to have if you want to be a writer. But the only real requirement is the ability to remember every scar.
Having a little talent as a writer is like having a little talent as a brain surgeon.
