“One of the great liabilities of history is that all too many people fail to remain awake through great periods of social change. Every society has its protectors of status quo and its fraternities of the indifferent who are notorious for sleeping through revolutions. Today, our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change.”
Dr. Martin Luther King, Jr.

More quotes from MLK:
“I have decided to stick with love. Hate is too great a burden to bear.”
“Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.”
“The true measure of a man is not how he behaves in moments of comfort and convenience but how he stands at times of controversy and challenges.”
Martin Luther King Jr. was an American Christian minister and activist who became the most visible spokesperson and leader in the Civil Rights Movement from 1955 until his assassination in 1968.
