We only have time, and every choice revolves around how we use our limited time. The document advises the reader to look forward, not backward, and to not rely on others or work as a substitute for making personal decisions about how to spend their time. It emphasizes that the reader must decide for themselves what success means, how much they leave to chance, and whether to stay isolated or engage with others. The reader is told to decide now, rather than later, how to use their time.
