I really do suggest you don't read this post if a) you have agent rejections on more than one book, b) you are feeling a little wavy in the confidence department, and/or c) you purchased Olive Lemon's tale, because she insists I be good to you.
Here's a scary thought...
You've written five not-that-good books that agents have taken an interested in, dedicated a little bit of their time to - and they remember your name, because agents are hot on things like that - and then you write a sixth book, but those agents sigh when they see your name and think, 'I don't think I'll bother this time, they always disappoint', but the sixth book is brilliant, and it's left to blow away in the wind with only tumbleweeds for friends.
Did your stomach just churn? A rejection sent that thought scurrying through my head today - and no, I haven't had five not-that-good books that agents have taken an interest in - only two (we don't talk about the early years). But I imagine that figure could elicit the same response.
P.S. If you live outside the US, you can now purchase Olive Lemon for $7.50 direct from the Bucket 'O' Guts website.
