milestone

A key milestone is the development of working memory or in Piaget terms 'Our realization of object permanence'.

Muslims recite the Shahada during important milestones and in everyday life: it’s part of the Adhan, the daily call to prayer, and is sometimes spoken over people at birth.

That operational efficiency allowed us to scale, and by 2020 we reached our first milestone, reaching 1 million people in Tanzania.

I never celebrated the milestones.

Now, boiling everything down to a single score like this makes it easy to get caught up in reaching the next milestone.
