Answer: Do what you can.

The world is made up of seven billion you’s and me’s. Every day, with every action, large or small, you are either adding to the sum of beauty, joy and understanding in the world—or you are subtracting from it.

Read the news lately? The headlines are full of bigotry, suspicion and fear. What can one person do? Just do what you can, and that will make a bigger difference than you might think. Here’s how:

When you and I think about the people around us, the world has more care in it.

When you and I stand up for what’s right, the world has more justice in it.

When you and I send a card or an e-mail to lift someone’s spirits, the world has more light in it.

When you and I control our temper, the world becomes more reasonable.

When you and I reach out and lend a hand, the world becomes more giving.

When you and I forgive a wrong, the world becomes more peaceful.

When you and I inspire or encourage a child, the world becomes more hopeful.

There is no such thing as a small influence, or a small act of kindness, or an unimportant person, or an unimportant day. You may not be able to see the impact of your actions, but it’s all connected and it all matters.

As William James put it: “Act as if what you do makes a difference. It does.”
