Humanity does not ask us to be happy. It merely asks us to be brilliant on its behalf.
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.
Your work is first, learning is first, winning is everything because without it there is nothing.
