Warren Buffett has lived a frugal lifestyle despite his immense wealth. He still lives in the modest house he purchased over 50 years ago and drives himself instead of using a private driver. Though he owns large companies, he delegates responsibility to competent CEOs and only communicates with them once a year through a short letter. Buffett advocates focusing on long-term investments and living within one's means rather than chasing status symbols or debt. He emphasizes finding fulfillment through personal interests and relationships rather than material goods or the approval of others.
