Humans tend to admire productivity; idleness, unless imposed by illness, is often despised. Indeed, those capable of balancing a variety of tasks are routinely praised.
"Doing nothing" is discouraged. One should be reading, working, exercising, catching up on the news, taking in some form of entertainment or otherwise engaged. "Idleness" is even considered to be sinful among those prone to mythology.
Yet, thought is the basis of creativity. Those caught up in duties or self-imposed activities do not have time for thought (other than thinking about what needs to be done next). They will never be artists, writers, inventors or philosophers.
