The year 2025 was one of the most remarkable years of my life. I felt compelled to capture it in a two-part article Series 1: A reflection on my journey to becoming a CST, and Series 2: A look back at the year as a whole. This is Series 1: A reflection on my journey to becoming a CST On May 1, 2025, in Munich, I heard the words that transformed a dream into reality: “Congratulations, you are an approved CST! You cleared the TAC in your first attempt” In that moment, I became CST. The feeling was no less than winning an Oscar. This journey of becoming a CST has been profoundly transformative—both as a trainer and as an individual. I experienced countless learnings, and here are a few reflections from that journey: (These learnings are entirely my own, based on my personal experience. They are not related to or directed at anyone else.) What This Journey Taught Me Key Takeaways From My TAC Interview and Simulation: This entire journey of preparing for the CST has been one of the most meaningful and enriching chapters of my professional life. Every co-training, every feedback session, every conversation with mentors, and every moment of self-reflection shaped me in ways I didn’t expect. Looking back, the journey was exciting, fulfilling, and transformative. It challenged me, inspired me, and expanded my horizons.
