Was it something I wrote?:
"Last week I got a response to an idea I sent to a prodco in February! I had actually forgotten I'd sent it. And that is the best way to handle it. Don't hang around waiting for phonecalls or responses. Move on. Get the next thing out. Don't think for one moment that what you have out there could be life changing [which it could] because the chances are stacked against it.
But keep writing. Keep getting your work out there. Because eventually, if you are talented, something will stick. It might be the third or fourth spec you've sent to a prodco and they seemed to have no interest in the previous submissions. But...... they will remember the name, the style, and the fact that you keep producing the goods. You don't just call yourself a writer - you are one. There are many who are in love with the idea of being a writer more than sitting down and cranking out the pages."
