Acres of Diamonds by Russell H. Conwell: is a metaphorical story about a man who had a vast land which he sold to go out and search for riches he wanted to create a lot of success for himself, so he went out to go searched for riches and then he struggled for many years to create that success that. He wanted to find those riches and then eventually did not end up achieving his dream and they realized afterward that the land that he sold actually contained a very rich source of diamonds in other words he had access to the opportunity.
The central idea of work is that you don't have to look elsewhere for opportunities, successes, or happiness-the resources to achieve all the good things in your community. This theme was developed through an anecdote of an introduction from an Arab leader to Conwell about a man who sold his property and went to waste to find a diamond because he was anxious to find one. The new owner of his house discovered an abundant diamond mine on the premises. Conwell elaborates on the subject with examples of virtues related to success, genius, service, or ordinary Americans.
