Creating Novelty

Creating novelty is just making a task, adding something different to a task. When there's tasks that need to be bedone over and over again, it's much faster to do. Yet, the problem of getting started with great enthusiasm and vigor and a great deal of interest, but then sing interest midway through a task or t maybe didn't a longer task. How does one keep their interest going when a task is taking more time than they thought? I find if i'm not feeling so well  doing it in bed is novelty enough for me.
