Work expands to fill the time available to do it.

A ten minute task will take an hour if that’s the amount of time that was given. I think the reverse implication is also true. Due to the Law of Diminishing Returns , a task that truly takes an hour may be more than 10% done if you’re only given 6 minutes to complete it.
