What can you give away freely and still have?

It’s been said that you can’t have your cake and eat it too. But you can’t very well have love without giving it. There are other examples of things you can give away freely, yet never run short of. Think about it. Some of them are of inestimable worth. Isn’t it empowering to think that some of life’s most precious things come in a never-ending supply?

What can you think of that we can give away yet still keep for ourselves? What can we only have through giving?
