In the 1990s, Faulkner honed his expertise as a modeler. He completed Perpetual Cybernetics, which differentiated the seven "worlds of subjective experience" that NLP uses as a basis for its presuppositions and techniques. In 1993, together with golf pro Mark Staples, he co-founded E.P.I.C Golf by modeling the internal and external behavior patterns of outstanding golfers. Later that same year, Faulkner co-authored and starred in the video "NLP in Action" and in 1994 he co-authored a book with Robert McDonald, entitled "Success Mastery with NLP", based on his work modeling 'flow states' and the behavior of exceptional achievers. He continued to develop "Perpetual Cybernetics" in conjunction with his "Living Myths & Metaphors" work to arrive at one, single, unified model: "the Metaphors of Perception". This work subsequently spawned several more models, including: "Worlds Within a Word, Rhythms of Time" (1995), and "Meta-Patterns" (1996).
