When did Mother Teresa write the poem "Do It Anyway"?

The well-known list of commandments "Do It Anyway," often attributed to Mother Teresa, was actually written by Kent M. Keith in 1968. It was published in a book for aspiring leaders as "The Paradoxical Commandments" while he was a student at Harvard.

Mother Teresa posted eight of the 10 commandments on a wall of the children's home she ran in Calcutta in the format of a poem. In her book "Mother Teresa: A Simple Path," Lucinda Vardey transcribed the writing from the wall. The sixth and eighth commandments were missing from the original version, and the title had been changed to "Anyway."
