Strong agreement

From this article written by Chris Mayer

One of my favorite investors was Phil Carret, who died in 1998 at the age of 101 and who worked at his art until almost the very end. He witnessed more than 30 bull markets and more than 30 bear markets over a lifetime of investing. Warren Buffett admired him, often inviting him to Berkshire's annual meeting and calling Carret the "Lou Gehrig of investing." (Gehrig was the "Iron Horse" of baseball, before his consecutive games played record fell to Baltimore's Cal Ripken Jr.).

When asked on the Louis Rukeyser show in 1995 what was the single most important thing he had learned about investing over his long career, Carret had a one-word answer: "Patience."
