“One smile has the power to...Calm fears.Soften stone walls.Warm a cold heart.Invite a new friend.Mimic a loving hug.Beautify the bearer.Lighten heavy loads.Promote good deeds.Brighten a gloomy day.Comfort a grieving spirit.Offer hope to the forlorn.Send a message of caring.Lift the downtrodden soul.Patch up invisible wounds.Weaken the hold of misery.Act as medicine for suffering.Attract the companionship of angels.Fulfill the human need for recognition.Who knew changing the world would prove so simple?”

It was caused, I thought, by people failing to love one another, failing to love their enemies.”

“Certain people have said that the world is like a calm pond, and that anytime a person does even the smallest thing, it is as if a stone has dropped into the pond, spreading circles of ripples further and further out, until the entire world has been changed by one tiny action.”

“There is no medicine like hope, no incentive so great, and no tonic so powerful as expectation of something tomorrow.”

“I thought it would not hurt to remind you that love is a powerful force in this world, invisible though it seems.”
