James I hope you don't keep feeling your self like this. I have a degree and I work a job where my educational qualifications do not meet my job description but that doesn't change the fact that I'm not an achiever. On the contrary you should look at it like a job and a place where you can built and perhaps apply for a higher position or enjoy well your job.

Being a cashier (I'm one too part of my job description) doesn't have to demeanor you in any way asking as it pays you a salary and it pays the bills. It's only 8 hrs. After that you can enjoy countless activities where you don't have to even think about your job.

Afterwork, I enjoy my life with my family and kid. I go to do multiple activities, I take my kid to the car, I look up the sky, look at the star and admire such wonderful things out there, like nature. I feed off the breeze of the park we go to, intake deep breaths and try to enhale them as cool breaths of joy. I'm definitely not thinking about my job status right now.

I hope this makes you feel better ok.
