He That Compares What He Has Done With What He Has Left Undone, Will Feel The Effect Which Must Always Follow The Comparison Of Imagination With Reality; He Will Look With Contempt On His Own Unimportance, And Wonder To What Purpose He Came Into The World; He Will Repine That He Shall Leave Behind Him No Evidence Of His Having Been, That He Has Added Nothing To The System Of Life, But Has Glided From Youth To Age Among The Crowd, Without Any Effort For Distinction.
