I am a great supporter of Mr. Yon and his work. There are few others out there who have even a single percent of his credibility in dealing with those who actually have boots on the ground.

Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press On' has solved and always will solve the problems of the human race.
Calvin Coolidge, President of the United States 1924-1929
