Acres of Diamonds

'Acres of Diamonds' is a classic self-help book written by Russell H. Conwell, first published in 1890. The book is based on Conwell's famous lecture, which he delivered over 6,000 times across the United States. It tells the story of a farmer who sells his land in search of diamonds, only to realize later that his own land was filled with diamonds – the idea being that opportunities for success are often right in front of us if we know where to look.
