Another thing to consider: there are a lot of bad companies out there. If you aren't turning down about 1/3 of the jobs that you are interviewing for, you're probably having trouble identifying the good places to work. Similarly, many times it will be a fine company, but just not a good fit for you. No shame in not being offered a job that won't be good for you!

Finally, it's a bit like finding a girlfriend/boyfriend. If you approach the exercise as some way of validating your worth, then you get a bit of a stink to you. Nobody really wants to start out a relationship that way. On the other hand if you are just keeping your eyes open for opportunities that are mutually beneficial things will go much more smoothly.
