I've seen someone who says he's just not motivated to do some important things and finds all the excuses in the world not to get those things done at that time while I just see all the ways they can be done there and then. I feel that's just laziness at play sometimes it's just annoying to see especially if it affects me directly. Taking a breather after a task is fine like you stated, but outrightly holding off tasks forever is just a bad habit one needs to break out of. This affects many facet of one's life in the long run.
