It's true, though.
I make my life difficult everyday by not believing in myself, by not querying and letting my e-mail dictate my self-worth. We are our own worst enemies. I believe that sincerely since it's so true in my case.
So, don't be so hard on yourself and realize that this is all a learning process. Some days will be good, others not as great, but in the end you will have earned published clips and enough wisdom to share.
Take care, kittycats!
