The sun’s rays do not burn until brought to a focus.” “Before anything else, preparation is the key to success.” “Sometimes we stare so long at a door that is closing that we see too late the one that is open.” “A man, as a general rule, owes very little to what he is born with – a man is what he makes of himself.” “The most successful men in the end are those whose success is the result of steady accretion.” “The nation that secures control of the air will ultimately control the world.” “America is a country of inventors, and the greatest of inventors are the newspaper men.” “Neither the Army nor the Navy is of any protection, or very little protection, against aerial raids.” “The nation that secures control of the air will ultimately control the world.” Thank you so much for watching.. please SUBSCRIBE for Latest Inspirational videos.
