Your identity is literally your “repeated beingness”: Technically, identidem is a word belonging to the Late Latin language. Also, thanks to Tamar Shippony, a reader of jamesclear.com, who originally told me about the etymology of the word identity, which she looked up in the American Heritage Dictionary.
We change bit by bit: This is another reason atomic habits are such an effective form of change. If you change your identity too quickly and become someone radically different overnight, then you feel as if you lose your sense of self. But if you update and expand your identity gradually, you will find yourself reborn into someone totally new and yet still familiar. Slowly—habit by habit, vote by vote—you become accustomed to your new identity. Atomic habits and gradual improvement are the keys to identity change without identity loss.

“behaviors followed by satisfying consequences”: This is an abbreviated version of the original quote from Thorndike, which reads: “responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce a discomforting effect become less likely to occur again in that situation.” For more, see Peter Gray, Psychology, 6th ed. (New York: Worth, 2011), 108–109.

The psychologist Gary Klein: I originally heard about this story from Daniel Kahneman, but it was confirmed by Gary Klein in an email on March 30, 2017. Klein also covers the story in his own book, which uses slightly different quotes: Gary A. Klein, Sources of Power: How People Make Decisions (Cambridge, MA: MIT Press, 1998), 43–44.

Museum curators have been known to discern: The story of the Getty kouros, covered in Malcolm Gladwell’s book Blink, is a famous example. The sculpture, initially believed to be from ancient Greece, was purchased for $10 million. The controversy surrounding the sculpture happened later when one expert identified it as a forgery upon first glance.
