What a wonderful phrase (and how true) I don't remember saying, as a child, that I wanted to be a writer. In fact, I had the same dreams as everyone else: fireman, superhero, doctor (to heal the world and help everyone). And I would "write" it all down as a little azimuth of what was coming to me.... And it's like you say:

One doesn't actually become a writer though-it's not a profession you choose-it's more a matter of Fate.
