It doesn't matter how hard or how many times you try if you do the same thing with the same attitude over and over again. In this case, you're applying for jobs and looking for companionship with the mindset that this is the 1000th time you've been in this position and the universe owes you a break, whereas to the recruiter or potential date this is the first time they've met you. What kind of impression do you think they're forming of you when you approach them with this mindset? Is it fair to them that they're just another potential notch in the litany of life failures instead of unique individuals and roles?
If applying to jobs and making friends isn't any easier after thousands of failures, you're not using failure as a learning experiment and your situation will never improve unless you recognize what it is that you're doing that's preventing you from having the kind of success you want to have.
