Read this. It won’t be a waste of time.
Time gets lost. People kill time. Time flies. It gets wasted. Time weighs heavy on our hands. We spend time. Time passes. It drags on or it hurries by. Those behind bars are said to be doing time. Sometimes, we have no time left; we’re out of time.…

There are four statements regarding control charts that are myths and in my experience, just refuse to die.
