A teacher. Which is lovely, because it shows how great the teachers are.
DD wants to be a jazz musician. She wants to compose, perform, arrange, and jam.
I have nothing against jazz musicians but the idea that everyone is investing a lot in her education so that she could one day make a living playing jazz in bars and clubs prompts me to have a second thought.
You're investing in her education so she becomes a happy resilient adult who's not afraid to try new things and who is interested in and enthusiastic about the world. Give me a happy relaxed jazz musician over a miserable, stressed out afraid to fail Nobel laureate any day.
