The only thing that can kill your spirit is doubt. But without doubt, you will never reach greatness...We all have the Raven in us.... The Raven by Edgar Allan Poe .... '' Open here I flung the shutter, when, with many a flirt and flutter, In there stepped a stately Raven of the saintly days of yore; Not the least obeisance made he; not a minute stopped or stayed he; ...... Then this ebony bird beguiling my sad fancy into smiling, By the grave and stern decorum of the countenance it wore, “Though thy crest be shorn and shaven, thou,” I said, “art sure no craven, Ghastly grim and ancient Raven wandering from the Nightly shore— Tell me what thy lordly name is on the Night’s Plutonian shore!” Quoth the Raven “Nevermore.” ............. And the Raven, never flitting, still is sitting, still is sitting On the pallid bust of Pallas just above my chamber door; And his eyes have all the seeming of a demon’s that is dreaming, And the lamp-light o’er him streaming throws his shadow on the floor; And my soul from out that shadow that lies floating on the floor Shall be lifted—nevermore!
