Data on the amounts of shareholder wealth created by Microsoft, Procter & Gamble, and other companies comes from the firm EVA Dimensions, which calculates these figures for most of the companies in the Russell 3000. Figures cited in this chapter are for February 5, 2008.
Data on Exxon Mobil's use of cash comes from 2006 financial statements. The quotation from CEO Rex Tillerson is from a personal interview conducted on March 1, 2007.
The quotation attributed to Josh Billings has been attributed also to Mark Twain, Artemus Ward, and other nineteenth-century American writers. Billings looks like the best bet to me, but if anyone has definitive evidence I'd love to know about it.

The story of Warren Buffett comes from having interviewed him formally and informally many times, as well as from the many articles about him by the great Carol Loomis of
Fortune.
One article remains especially insightful: Carol J. Loomis, “The Inside Story of Warren Buffett,”

Chapter Three: How Smart Do You Have to Be?
The academic paper first describing the experiment involving the undergraduate SF is K. A. Ericsson, W. G. Chase, and S. Faloon, “Acquisition of Memory Skill,”
Science 208
(1980), 1181-82. The research has been described at greater length in a number of other papers. In addition, I spoke with Professor Ericsson about the experiment, and he provided an audio tape of the session on July 11, 1978, which I describe in this chapter.

The finding that some chess players at the international master level possess below-average IQs is one of the most surprising and intriguing in this field. It is in J. Doll and U. Mayr, “Intelligence and Achievement in ChessâA Study of Chess Masters,”
Psychologische Beiträge 29
(1987), pp. 270-89.
The research on chess players and how well they can recall the positions of pieces on the board has proven to be extremely important in the study of great performance because it reveals that the seemingly incredible memories of chess experts are developed and specific to chess, not innate and general. Three researchers built the foundation of this work. One was a Dutch researcher, A. D. de Groot, whose doctoral dissertation was written in 1946 but not translated into English until 1965. The other two are William Chase and Herbert Simon, whose research showed that chess experts could remember the positions of many pieces in actual chess positions but were scarcely better than novices at remembering the positions of pieces placed randomly. See A. D. de Groot,

Chapter Four: A Better Idea
The basic facts of Jerry Rice's biography are very widely available in any number of published accounts. The specifics of his records are from

The study of violinists at the Music Academy of West Berlin is part of a highly influential paper that has become the foundation of the deliberate practice framework: K. Anders Ericsson, Ralf Th. Krampe, and Clemens Tesch-Römer, “The Role of Deliberate Practice in the Acquisition of Expert Performance,”
Psychological Review 100,
no. 3 (1993), pp. 363-406.
Chapter Five: What Deliberate Practice Is and Isn't
The specific elements of deliberate practice are all to be found in the description presented in the foundational paper cited above, though these elements are not discussed individually at length. The elements are considered more deeply in a number of later papers; a good introduction, with references to other research, is K. Anders Ericsson, “The Acquisition of Expert Performance: An Introduction to Some of the Issues,” in K. Anders Ericsson, ed.,
The Road to Excellence: The Acquisition of Expert Performance in the Arts and Sciences, Sports and Games
(Mahwah, N.J.: Lawrence Erlbaum Associates, 1996).
The account of Moe Norman is from a chapter in the book cited above: Janet L. Starkes, Janice M. Deakin, Fran Allard, Nicola J. Hodges, and April Hayes, “Deliberate Practice in Sports: What Is It Anyway?”
The account of Chris Rock's preparation for his New Year's Eve performance at Madison Square Garden, illustrating all the elements of deliberate practice, is David Carr, “Hard at Work on New Year's Eve,”

The description of how professional singers experience a singing lesson very differently from the way amateurs do is from C. Grape, M. Sandgren, L. O. Hansson, M. Ericson, and T. Theorell, “Does Singing Promote Well-being? An Empirical Study of Professional and Amateur Singers During a Singing Lesson,”

Until the expert performance research of the past thirty years, the prevailing view among psychologists was that performance at its highest level was largely automatic. The standard description is in P. Fitts and M. I. Posner,
Human Performance
(Belmont, Calif.: Brooks/Cole, 1967).
The opposite view, that top performers reach their high levels of achievement in part by avoiding automaticity, is described in K. Anders Ericsson, “The Influence of Experience and Deliberate Practice on the Development of Superior Expert Performance,” in K. Anders Ericsson, Neil Charness, Paul J. Feltovich, and Robert R. Hoffman, eds.,
The Cambridge Handbook of Expertise and Expert Performance
(New York: Cambridge University Press, 2006).
Chapter Six: How Deliberate Practice Works
The original work on how an expert tennis player predicts the flight of his opponent's serve based on cues in his posture is C. M. Jones and T. R. Miles, “Use of Advance Cues in Predicting the Flight of a Lawn Tennis Ball,”

(1978), pp. 231-35.
Similar findings have since been produced in several other sports. For a recent discussion of the general topic, see A. Mark Williams, Paul Ward, and Nicholas J. Smeeton, “Perceptual and Cognitive Expertise in Sport: Implications for Skill Acquisition and Performance Enhancement,” in A. Mark Williams and Nicola J. Hodges, eds.,
