Even if I couldn't get my early novels published, I could still write. I went into newspapers, where I got paid to write every day. If there's a better school for would-be novelists, I don't know what it is.
Once you're halfway home, you know that you can probably get the rest of the way there.
If you enjoy math and you write novels, it's very rare that you'll get a chance to put your math into a novel. I leapt at the chance.
