Don't have a full 17 minutes to watch one of the most important speeches in American history, (which of course means you won't be on social media today, etc., because you're so busy), then you can read it here.
Too busy for either? Here are some popular quotes from MLK:
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
If you can’t fly then run, if you can’t run then walk, if you can’t walk then crawl, but whatever you do you have to keep moving forward.
Injustice anywhere is a threat to justice everywhere.
Our lives begin to end the day we become silent about things that matter.
The time is always right to do what is right.
I look to a day when people will not be judged by the color of their skin, but by the content of their character.
The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.
In the end, we will remember not the words of our enemies, but the silence of our friends.
I have decided to stick with love. Hate is too great a burden to bear.
