Quote of the day by Andrew Carnegie: Andrew Carnegie’s $310 billion inflation-adjusted fortune proves his "one basket" rule works. Most businesses fail by scattering resources. Carnegie focused solely on steel. This singular focus slashed production costs by 89%. He moved from a penniless immigrant to the world's richest man. His strategy? Master one niche completely. Do not diversify too early. High-concentration leads to market dominance. Today, top CEOs still follow this blueprint. Focus creates expertise. Expertise creates wealth. Watch your basket closely to win.
