The poem describes an impossible dream of striving for lofty goals that seem unattainable and facing difficulties with perseverance. It discusses dreaming the impossible, fighting unbeatable foes, enduring unbearable sorrow, and going where others dare not. The dream is to right wrongs, love from afar, and try when weary, reaching for unattainable stars. This is the singer's quest to follow their star no matter how hopeless or far it may seem.
