Sports psychology books split into two camps, and knowing which camp a book sits in tells you most of what it can do for you.

Inner-game books are about you: nerves, focus, confidence, routines, bouncing back from mistakes. They're the bulk of the genre, and most of them are good. Outer-game books are about the person across from you: reading the game, reading an opponent, making them uncomfortable, and choosing the tactics that actually win. Far fewer of these exist, and they're what most athletes are missing once their nerves are under control.

A full disclosure before the list: this site exists to sell one of the outer-game books, Edge. It's at the end, with the reasons it belongs here. Everything else is a book we'd recommend whether or not you ever buy ours.

The inner game

The Inner Game of Tennis

W. Timothy Gallwey

The book that started the genre. Gallwey splits every player into Self 1, the anxious voice giving instructions, and Self 2, the body that already knows how to hit the ball. Most of the book is about getting Self 1 out of the way. It's written about tennis, and it applies to anything you do with your body under pressure.

Mind Gym

Gary Mack with David Casstevens

Short chapters, one idea apiece, built for athletes who don't read much. Easy to pick up between practices, which makes it a good fit for a teenager's gym bag.

The Champion's Mind

Jim Afremow

A sports psychologist's practical playbook: routines for confidence, focus, handling pressure and recovering from mistakes. Broad rather than deep, and very usable.

With Winning in Mind

Lanny Bassham

Written by an Olympic gold medalist in rifle shooting, a sport where nerves show up directly on the target. The focus is self-image and mental rehearsal. Precision-sport athletes, and chess players, tend to love it.

Mental Toughness for Young Athletes

Moses Horne and Troy Horne

Aimed squarely at kids, with simple exercises for pre-game nerves and confidence. A sensible first book for a younger athlete before they're ready for something denser.

Learning how to learn

The Art of Learning

Josh Waitzkin

Waitzkin was the chess prodigy behind Searching for Bobby Fischer, and he later won world titles in Tai Chi Push Hands. The book is about how to get very good at something, and it's the best bridge on this list between the chessboard and combat sports. Any competitor who's hit a plateau should read it.

The outer game

Playing to Win

David Sirlin

Written by a fighting-game player and game designer, and the source of the term scrub: the player who loses to self-imposed rules about what's "cheap." Short and blunt. It's the clearest argument anyone has written that a competitor should use everything the rules allow.

The Book of Five Rings

Miyamoto Musashi

A legendary duelist's notes on strategy, written in the 1640s. Dense and strange in places, and it rewards rereading. Musashi was also a master at getting inside opponents' heads, which is a big part of why competitors keep coming back to him.

Edge: The Art of Ruthless Competition

Theta | Our book

Edge builds on Sirlin's ideas and extends them into a full system, drawn from chess, wrestling, jiu-jitsu, boxing, MMA, poker, team sports, military strategy and esports. It comes in three parts: Play the Game (reading situations and knowing what they're worth), Play the Player (breaking down an opponent's decision-making with a framework called VUCA: volatility, uncertainty, complexity and ambiguity) and Play for Blood (dropping scrub habits, losing in practice on purpose, and using pressure). The closing chapters cover cheating, the price serious competition asks of you, and why life isn't a game.

If the books above teach an athlete to hold their nerve, Edge teaches them what to do with it.

Which one to read first

  • A younger kid just starting to compete: Mental Toughness for Young Athletes.
  • A teen who gets nervous and tight in matches: Mind Gym or The Inner Game of Tennis.
  • A competitor who's stopped improving: The Art of Learning.
  • A competitor with plenty of skill who keeps losing to people they should beat: Playing to Win, then Edge.

Two more for the curious

Neither of these is a sports book, and Edge draws on both. Antifragile by Nassim Taleb explains how some systems get stronger from shocks and volatility, which is exactly what you want from a competitor. The Grasshopper by Bernard Suits is a short, funny piece of philosophy that defines playing a game as "the voluntary attempt to overcome unnecessary obstacles." It's the best explanation of why games matter, and why they shouldn't matter too much.
