Jo Ann Corkran applies a self-designed mistake notebook discipline where she keeps a written record of errors to separate emotional reaction from factual analysis and avoid repeating the same mistakes, illustrating a highly structured, self-reflective decision-making approach that she also encourages in entrepreneurs. She has intentionally reinvented her career roughly every decade—shifting from public fixed-income asset management to private placement equity—so she's unusually comfortable with major career pivots and brings that same mindset to guiding founders through significant strategic shifts.
