“Compassion is a muscle that gets stronger with use.”

“Compassion is a muscle that gets stronger with use, and the regular exercise of choosing kindness over cruelty would change us.”

“Flex that muscle in your heart. The important thing is that it becomes your compass...”

“What is wrong with looking muscular? Muscles are beautiful. Strength is beautiful. Muscle tissue is beautiful. It is metabolically, medically, and philosophically beautiful. Muscles retreat when they're not used, but they will always come back if you give them good reason. No matter how old you get, your muscles never lose hope. Few cells of the body are as capable as muscle cells are of change and reformation, of achievement and transcendence.”

“Courage is like a muscle. We strengthen it with use.”

“Courage is very important. Like a muscle, it is strengthened by use.”
