Example is not the main thing in influencing others. It is the only thing.
by Albert Schweitzer （アルベルト・シュバイツァー）
Albert Schweitzer (January 14, 1875-September 4, 1965) was born into an Alsatian family which for generations had been devoted to religion, music, and education. His father and maternal grandfather were ministers; both of his grandfathers were talented organists; many of his relatives were persons of scholarly attainments.
