We must accept life for what it actually is - a challenge to our quality without which we should never know of what stuff we are made, or grow to our full stature.
Remember one very fundamental thing about life: Any experience that has not been lived will hang around you, will persist: "Finish me! Live me! Complete me!" There is an intrinsic quality in every experience that it tends and wants to be finished, completed. Once completed, it evaporates; incomplete, it persists, it tortures you, it haunts you, it attracts your attention. It says, "What are you going to do about me? I am still incomplete - fulfill me!"
Wearing the white flower of a blameless life, Before a thousand peering littlenesses, In that fierce light which beats upon a throne, And blackens every blot.
Mankind is drawn to the heavens for the same reason we were once drawn into unknown lands and across the open sea. We choose to explore space because doing so improves our lives, and lifts our national spirit. So let us continue the journey.
