He introduces his "Terrier and Monkey" theory for internal drive and explains the "Two Cups" balance that every high-performer must master to move from luck to true experience. Drawing on his 105 consecutive Ironmans, Sean reveals why physical fitness is only one of 10.5 essential pillars and how the "Marginal Effort Trap" can sabotage even the elite. From redefining the meaning of a DNF to the importance of "The Middle," Sean shares a straightforward blueprint for anyone looking to set audacious goals and actually see them through.
