The document discusses the "Law of the Seed" - that not all seeds planted will grow, just like not all efforts and attempts in life will succeed. It takes many tries to achieve something, whether that's getting a job through many interviews, finding a good employee through many interviews, or selling something through many conversations. When we understand this law of nature and that failure is part of the process, we don't get as disappointed by setbacks. Successful people understand this and are willing to plant more seeds through more attempts and efforts. It's important to have preferences for how we want things to go but also accept when things don't go our way instead of getting angry or frustrated by events we can't control.
