Uber life sometimes sucks

So uber is a "cab" company. There are both good and bad things about it. I drive for uber, and I had a tough day. So one of my customer was being really annoying and he said, "if you have a degree, why do you not have a job" etc and then he said "I only have a high school education and am in (some sheriff program) blah blah" and all this time I was getting really pissed at him. He has no idea that it's what I struggle with everyday and it's so easy for him. I just have not had the best luck. I have applied to so many jobs, and I have had maybe a dozen interviews. But it seems either they think I am over qualified or I lack job skills, which is it? I am beyond frustrated and am just about to give up!
