The characteristic of being idle or relaxed can be called laziness. Your laziness might keep you from taking your puppy for the long walk she needs, instead just letting her out in the yard.
There's the kind of laziness when you lie in a hammock for an hour watching the clouds, and then there's the kind when you don't get any work done all week. You might experience laziness on vacation, sleeping later than usual and lounging on the beach with a book. Sometimes laziness is the result, though, of an unwillingness to work or help someone out: "His laziness meant that I had to set the tent up all by myself!"
