Ralph Waldo Trine was an important New Thought writer. Trine is often cited as the inspiration for Napoleon Hill's 'Think and Grow Rich'. As with all New Thought writers, Trine's work helped to shape the current crop of self-help books, such as 'The Secret', 'The Power of Positive Thinking', and 'The Law of Attraction'.
