But in the meantime I became accustomed to the writing life and it would be hard to change now - partly because of the salary cut if I went to my other love, teaching; and partly because I still have stories to tell, even though it isn't all that fun doing the work anymore.
I fell into playwriting accidentally, took some classes in it, and also took creative writing classes, but I really didn't expect it to be a career because I didn't believe there was a way to make money as a playwright without being lucky and I didn't feel particularly lucky.
There's a reason why every human society has fiction. It teaches us how to be 'good,' to behave in a way that is for the benefit of the whole community.
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.
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.
