"If I can stop one heart from breaking,
I shall not live in vain;
If I can ease one life the aching,
Or cool one pain,
Or help one fainting robin
Unto his nest again,
I shall not live in vain."
Life, p. 6 - Collected Poems (1993)
American lyric poet Emily Dickinson died #OTD in 1888. Although she wrote 1789 poems, only a few of them were published in her lifetime, all anonymously, and some perhaps without her knowledge.
