Write a Personal Reflection After a Big Career Year

Act as a reflective practice coach. The year is ending and I want to do a deep annual career reflection to extract lessons and set a clear direction for next year. Here is a summary of my major experiences, wins, setbacks, and decisions from the past 12 months: [YEAR_REVIEW]. Guide me through a structured reflection covering: the 3 biggest lessons learned, the moment I am most proud of and why, the decision I would make differently, the one thing I am carrying forward as a non-negotiable, and my single most important focus for next year.
