Cool quote about growing up

"As of this writing i am sixty-one years old in chronology. But I am not an isolated, chronological numerical statistic. I am sixty-one, and I am also four, and twelve, and fifteen, and twenty-three, and thirty-one, and forty-five, and..and...and....If we lose any part of ourselves, we are thereby diminished. If I cannot be thirteen and sixty-one simultaneously, part of me has been taken away. For growing up never ends; we never get there. I am still in the process of growing up, but I will make no progress if I lose any of myself on the way."

- Madeleine L'Engle
