I am the only one who leaves
You may as well think about it as an incessant spell of leaving: You leave from childhood, teenage, youth and the rest of your life as up to the hour, minute and second. If one's life has a defining moment, yet he/she is floating away from the defined moment to many a cursed ones too. The "I" in me is in a state of infinite flux. And I might lose it at some point in time.
Consider this poem from the Peruvian poet Cesar Vallejo. He is one good poet you want to read even if you don't like poetry and hate one time communists.
Paris, October 1936
From all of this I am the only one who leaves.
From this bench I go away, from my pants,
from my great situation, from my actions,
from my number split side to side,
from all of this I am the only one who leaves.
From the Champs Elysées or as the strange
alley of the Moon makes a turn,
my death goes away, my cradle leaves,
and, surrounded by people, alone, cut loose,
my human resemblance turns around
and dispatches its shadows one by one.
And I move away from everything, since everything
remains to create my alibi:
my shoe, its eyelet, as well as its mud
and even the bend in the elbow
of my own buttoned shirt.
