What bpcyclist said! Not to sound like
Kristen Wiig's SNL character Penelope who one-ups everyone with her "I did that too..." but I actually met J.K. Rowling and her daughter while traveling on a train from London to the Lake District. I didn't know who she was at the time. I just remember she introduced herself as Jo Rowling (she didn't mention her Harry Potter books to me either). I gave her daughter some slices of my orange and we chatted about writing and about travel. I told her I was going up to the Lake District with some badly written poetry of my own, because I'd just been there the January before on a 3-week literary ventures by train college course, and had come from Galway where my family had a reunion. So, it was all timing. Only when I got back to the States, and saw her first Harry Potter book on the shelf, did I realize who sat across me in that train car traveling to the Lake District.
So, write your novel! Someone will publish it. But you have to finish it first.
