The philosophy of laziness

I often wonder to myself what the moral principles behind laziness are. Just a moment ago, I was sitting on a bench waiting for the elevator, and as I waited, the bench and I became one. I couldn't get up except with the extreme motivation to hurry up and be on time. I often wonder to myself if we all undergo moral struggles in our head relating to the lack of physical movement for the enjoyment of rest. I personally weigh the situations in my head, but never come to a true conclusion until I realize I have to scrap what I'm thinking and just get up. But I want to hear from you all; is there some philosophical explanation for the laziness we all experience?
