Charlie Munger's 'Iron Rule of Life' and What It Means for Wealth
The late Berkshire Hathaway vice chairman outlined a core principle he credited with enduring success. Here's what it means for investors.
Charlie Munger, the late vice chairman of Berkshire Hathaway and longtime partner of Warren Buffett, was known for distilling complex ideas into blunt, practical maxims.
