A milestone is a marker of progress, not just a random task; it usually signifies the completion of a major phase.

The story behind the word. In Ancient Rome, 'miliaria' were stone pillars placed every mile along roads to tell travelers how far they had come and how far they had to go. We now use the term for metaphorical journeys.
