The 21 Irrefutable Laws of Leadership
The 21 Irrefutable Laws of Leadership: Follow Them and People Will Follow You is a 1998 book written by John C. Maxwell and published by Thomas Nelson.
 It is one of several books by Maxwell on the subject of leadership.
 It is the book for which he is best-known.
 The book was listed on "The New York Times" Best Seller list in April 1999 after marketing company ResultSource manipulated the list by making it look like copies of "The 21 Irrefutable Laws of Leadership" had been purchased by thousands of individuals when, in actuality, ResultSource had simply made a bulk order of the book.
 The book had sold more than one million copies by 2015.
 Christian businessperson John Faulkner was inspired to found Christian business magazine "TwoTen" when he read "The 21 Irrefutable Laws of Leadership".
 Professional basketball player Harrison Barnes read and spoke positively of the book.
 Annie Grevers of "Swimming World Magazine" wrote of Maxwell's book, "it's cheesy, but ... it did me some good".
 Columnist Michael Hiltzik of the "Los Angeles Times" criticized Maxwell for including in the book "the insidious subtext ... that externalities have nothing to do with your failure", an assertion that Hiltzik argues research studies have demonstrated to be false.

 In the conference semi-finals, the Mavericks run was motivated with a sweep of the champions of the previous two seasons, the Los Angeles Lakers.

 After a loss in Game 3, the Mavericks won the last two games in Dallas to take a 3–2 series lead heading to Game 6 in Miami.
 The Mavericks won their first NBA Championship in Game 6 to clinch the first major sports championship in the Dallas-Fort Worth area since the Dallas Stars in 1999, and the first title in Mavericks franchise history.
 The Mavericks are the third team to win an NBA title in the state of Texas, joining the Houston Rockets and San Antonio Spurs.
 The Mavericks are also the third team to win a major sports championship in the Dallas-Fort Worth area, joining the Dallas Cowboys' five Super Bowl titles and the Dallas Stars' only Stanley Cup, leaving the Texas Rangers as the only team to not win a major sports title in the area, as they have not won the World Series.
