Your work is first, learning is first, winning is everything because without it there is nothing.
The education that prepared me was my general education classes, which I tried to avoid when I was a stupid undergraduate, but which gave me the foundation of general knowledge that makes a career as a writer possible.
The most important training, though, is to experience life as a writer, questioning everything, inventing multiple explanations for everything. If you do that, all the other things will come if you don’t, there’s no hope for you.
