In the traditioning of everything sounding more profound in Latin: Horace used "ab ōvō" and "in mediās rēs" to define where stories start.
"Ab ōvō" means "from the egg". From start to finish.
"In mediās rēs" starts in the thick of things. From the middle outward.
Our life story has a clear Ab ōvō moment. Our end is unclear.
Where we are today is in the thick of things.
We get to live from this middle, outward.
