  • A founding classic of the self-help genre, still among the most widely read books on personal growth.
  • Argues that a person's outer life (health, success, and circumstances) grows out of their inner thoughts, so changing how you think is the way to change your life.
  • Argues that people are not victims of their situation, because steady, focused thinking toward a clear purpose builds strong character and real achievement.
  • Helped shape the "New Thought" style of self-help writing that led to later bestsellers such as "Think and Grow Rich" and "The Power of Positive Thinking."
  • Its core idea, that thoughts drive feelings and actions, is echoed in the motivational speaking and success coaching industries that grew up in the following century.

  • Title borrowed from the Bible

    The title echoes Proverbs 23:7, which says, "For as he thinketh in his heart, so is he."

  • Written by the sea

    Allen wrote it in Ilfracombe, a small seaside town in England, after leaving office work to write full time.

  • Short enough for one sitting

    The whole book is seven short chapters, and most readers can finish it in about an hour.

  • Fame came after him

    Allen died in 1912, and most of the book's worldwide spread came in the decades after his death.
