I have to second the general notion that this is a numbers game. My own statistics right now show that for every 100 applications, I get 12 applications with at least one interview, and 3.5 applications with an offer. Those numbers are not great but statistically, if you apply to enough jobs, you can see that you have a good shot of getting at least one offer. Of course, that may require hundreds of hours of work. But if you calculate the odds yourself, you can see there is an end in sight, even if it is quite far away.
