I completely agree that obsessing about a clean house all day long is probably not a good use of time.
On the other hand, many studies show that people tend to be more relaxed and content when their home is clean *to a certain degree*. They also save a ton of time because now they can find what they need to find. Their health also improves.
So the key is not to clean obsessively
However, there is a way to clean efficiently so you spend a minimum of time and keep your serenity, health, and time usage as top notch as possible!
That's of course a prime topic for our cleaning forum area, on how to do that
