Very good for you to draw from the inspiration of MLK, who fought so hard along with many others. Remembering people like him helps me too.
Here is a Harriet Tubman quote that helps to put things in perspective for me.
“If you hear the dogs, keep going. If you see the torches in the woods, keep going. If there's shouting after you, keep going. Don't ever stop. Keep going. If you want a taste of freedom, keep going.”
