I never really learned to stop. You just work until the job is done and find the next thing. Doing nothing? I don’t know, there is always something. So yeah, unproductive is a good word for it. It’s all about the words, isn’t it? A “lazy day” is ignoring work. Even when I take the time to play golf or ride a bike, I’m doing something.
There’s a difference between sleeping in and being lazy.
