If we can sacrifice our sleep to work for humanity, we should do it. If by having not such good food we can share with another, we should do it. If by having not such a nice dress we can give a dress to one who needs it, we should do it. If by having one dish instead of many we can share with someone who needs it, we should do that. If we can sacrifice our pleasures, our theaters, to give to others we should do it. We can sacrifice our anger when anger comes upon us. We can sacrifice our pride. We can bow to those who think little of us. There are many sacrifices that do not cost one penny. We can give some of our time if we cannot afford a great generosity. We can give our patience to those who need our patience. To those who want some liberty - very well, we can give liberty. I think all this is worthwhile sacrifice: we should do it.
