Journey

The term originates from military procedure. A 'muster' was a formal assembly of troops, often to verify that the soldiers were present and properly equipped. A soldier who 'passed muster' successfully underwent this inspection without being found lacking. Over time, the phrase moved from the barracks into general use to describe anything that meets a required standard of quality.
