Investors urged to focus on a stock's future potential, not past gains, says Jim Cramer.

Jim Cramer advises investors to stop fixating on how much a stock has already risen and instead focus on its future growth potential. He cites examples like Corning and Arm Holdings, which he bought after significant price increases because he believed their business stories still had room to grow. Cramer emphasizes that a stock shouldn't be considered too expensive just because it has already gained value, encouraging investors to prioritize the company's future prospects over past performance.
