At the beginning, between twelve and eighteen I didn't want to become a nun. We were a very happy family. But when I was eighteen, I decided to leave my home and become a nun, and since then, this [sic] forty years, I've never doubted even for a second that I've done the right thing, it was the will of God. It was His choice.

(Mother Teresa, The Private Writings of the 'Saint of Calcutta')
