Im stressed and exhausted

Why do I have to be an honest person? Most people with my new job would love it because you just walk around doing nothing most of the day. But I can’t do that, I want to work at my job and need to stay active. I spent the last two hours today doing absolutely nothing but walking around and it went so slowly and drove me insane. The boss says he’s amazed by my work when all I did was the basics and did stuff just to be busy. I left my last job for this exact problem but I really don’t want to leave this one because it pays so well and everyone is really nice. I just can’t be the kind of person who’s done with everything halfway through the day and then spends hours doing nothing. Im just looking for actual work to do at work. I had jobs like that before and wish I could go back to them but they don’t pay as well. This job has a relaxed environment, great pay, nice people and good hours but just not a lot to do.
