Richard Bach's quote

Richard David Bach (born June 23, 1936) is an American writer. He is widely known as the author of the hugely popular 1970s best-sellers Jonathan Livingston Seagull and Illusions: The Adventures of a Reluctant Messiah, among others. His books espouse his philosophy that our apparent physical limits and mortality are merely appearance. He claims to be a direct descendant of Johann Sebastian Bach. He is noted for his love of flying and for his books related to air flight and flying in a metaphorical context. He has pursued flying as a hobby since the age of 17.

Your only obligation in any lifetime is to be true to yourself. Illusions: The Adventures of a Reluctant Messiah
