P. T. Barnum

"No man has a right to expect to succeed in life unless he understands his business, and nobody can understand his business thoroughly unless he learns it by personal application and experience."

"The show business has all phases and grades of dignity, from the exhibition of a monkey to the exposition of that highest art in music or the drama which secures for the gifted artists a world-wide fame princes well might envy."

"The foundation of success in life is good health: that is the substratum fortune; it is also the basis of happiness. A person cannot accumulate a fortune very well when he is sick."
