John D. Rockefeller became the first billionaire in modern history through his business success, but later suffered immense pain and illness in his 50s. He realized he could not keep his wealth and decided to focus on giving it away through philanthropic causes. His health improved as he donated to hospitals, schools, and missions. Rockefeller lived to age 97 and found true happiness and peace through generosity, showing that non-financial success can be found by helping others with resources and time.
