Making a Difference and Living a Better Life

To make a difference in the world and live a better life, one should focus on solving problems that are personally interesting and meaningful, rather than following someone else's problem or pursuing a problem for external reasons. Historical examples such as Norman Borlaug, Faraday, and Newton demonstrate that solving important problems often arises from intrinsic interest and curiosity. There is no guaranteed formula for success or happiness, but following personal curiosity and passion can lead to optimism and a fulfilling life.
