Almost every time Warren Buffett makes a TV appearance or issues a letter to shareholders of Berkshire Hathaway (BRK.B 0.21%), he gives us a dose of his seemingly infinite investing wisdom. One of Buffett's most famous adages is the notion of holding a stock "forever." However, Buffett may not have been in the first investor to shout to the masses that if the proper work is done before buying a stock, selling won't need to be part of the equation. 

In this video, Fool financial analysts David Hanson and Matt Koppenheffer discuss this notion and one of Buffett's favorite stocks that they don't see him ever selling.
