Back in the beginnings of my career, I’ve had a job or two like that and it drove me bananas. I couldn’t stand the tedium, so I left to find “greener pastures”. It took me several years, and burning out twice (twice) before I landed on my boring and mundane job that I have now. It’s not even the job itself; it’s the company and their chill attitude. I’m not going anywhere else if I can help it.
