Seriously this is something you have to start figuring out. Nobody can get refused hundreds of times and not get into self-doubt. Once out of a few referrals, I actually take the time to write back to whoever refused, even if it's a dead mailbox, just so I can tell to myself hey buddy, look at how I can do this job. I take their offer line by line and tell them why I am the best to do it. Come to think of it, I should do that for cover letters.
