Build a Late-Career Reinvention Plan

Act as a career reinvention coach. I am a [CURRENT_ROLE] with [YEARS] years of experience and I feel stuck or unfulfilled. I want to reinvent my career in the next 3 years in a direction that is more meaningful and sustainable. My non-negotiables are [NON_NEGOTIABLES] and my biggest fear about change is [FEAR]. Design a phased reinvention roadmap: Phase 1 (explore and test), Phase 2 (build and transition), Phase 3 (fully commit). Include low-risk experiments I can run while still employed.
