"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."

— Emily Dickinson

If I can serve even one amongst you in his or her endeavour towards self-discovery, I shall not have lived in vain. Nay, my life on earth will have found its purposeful meaning.
