These Stanza of a poem by Robert Frost was known to be very dear to Nehru. He had handwritten this stanza and kept it with him at all times. It gave him inspiration in the darkness and gave him hope where there is none in sight.Hope this gives you the motivation to work hard.
“The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.“
