My first coach was 17 and I loved her. I started skating as an adult and I first met her when she was 15 and she was in my "13 and up" group class. When I decided to start private lessons I chose her because I felt she know exactly what I knew from the class and what I was missing, I was intimidated by "serious" coaches and she was cheaper. But I was very happy with her instruction, she was knowledgeable (working on her senior moves and gold dances) and compared with older coaches she had more enthusiasm and she was teaching from the point of view of somebody who was still learning, so she gave me better answers on how to handle frustration, how to manage my time, energy, expectations...
