Think and Grow Rich is a guide to success by Napoleon Hill, which was first published in 1937 following the Great Depression.
It was immediately welcomed as an antidote to hard times and remained a bestseller for decades.
Many people still find its philosophy of positive thinking and its specific steps for achieving wealth both relevant and life-changing.
Hill contends that our thoughts become our reality, and offers a plan and principles for transforming thoughts into riches, including visualization, affirmation, creating a Master Mind group, defining a goal, and planning.
