This is the true joy of life-the being used for a purpose recognized by yourself as a mighty one, the being thoroughly worn out before you are thrown to the scrap-heap; the being a force of nature instead of a feverish, selfish clod of ailments and grievances.
Remember that you are a human being with a soul and the divine gift of articulate speech: that your native language is the language of Shakespeare and Milton and The Bible; and don't sit there crooning like a bilious pigeon.
