Since I don't actually have a book out right now, and judging by you kind people who've actually left comments, there's a lot of writers out there looking to get their work published. I'm picking up a thread off Sarah's website actually, but it did make me think.
It WILL happen.
I've been rejected. EVERYONE'S been rejected. No-one's that good. But if you check my website I've shown a before and after sample of my writing. What's very interesting is that you CANNOT judge you're work objectively at the time, you can only judge it looking back, once you've improved.
Get rejected. Collect all those impersonal slips writing by the sixteen-year-old intern who's power belies her dress size. You'll be upset. Your feelings will be hurt and you'll doubt yourself. Maybe you aren' that good. YET. So what? Just think of all those other writers who quit at this point, all those rivals who WON'T be around next year to queer the pitch, while you're writing, writing and writing. But it does come back to the most fundamental point. You must love writing. Wholly and totally. To the point of irritation to your partner, friends and children. Take this blog, right now. I'm sure I have more important things I should be doing, but I can't help it. Only the desperate NEED to write will get you through the rejections.
