I love reading Wikipedia which led me to Wikiquotes.

20th century favorites are Gandhi, Einstein, Vera Brittain, Martin Luther King Jnr. and John Lennon.
My Favourite quote is
"An Individual has not started living fully until they can rise above the narrow confines of individualistic concerns to the broader concerns of humanity. Every person must decide at some point, whether they will walk in light of creative altruism or in the darkness of destructive selfishness. This is the judgment: Life's most persistent and urgent question is: 'What are you doing for others?' As quoted by Coretta Scott King in The Words of Martin Luther King, Jr.: Second Edition (2011), Ch. "Community of man", p. 3"
A good one from Gandhi is
"Thus the devotion required by the Gita is no softhearted effusiveness. It certainly is not blind faith. The devotion of the Gita has the least to do with the externals. A devotee may use, if he likes, rosaries, forehead marks, make offerings, but these things are no test of his devotion. He is the devotee who is jealous of none, who is a fount of mercy, who is without egotism, who is selfless, who treats alike cold and heat, happiness and misery, who is ever forgiving, who is always contented, whose resolutions are firm, who has dedicated mind and soul to God, who causes no dread, who is not afraid of others, who is free from exultation, sorrow and fear, who is pure, who is versed in action and yet remains unaffected by it, who renounces all fruit, good or bad, who treats friend and foe alike, who is untouched by respect or disrespect, who is not puffed by praise, who does not go under when people speak ill of him, who loves silence and solitude, who has a disciplined reason. Such devotion is inconsistent with the existence at the same time of strong attachments"
