This!
My D pivoted away in HS from wanting to go to conservatory when lessons, composition, and competitions were “sucking the joy” out of playing. Her expression, not mine. She said it was work and no longer a pleasure. The joy returned after a studio/instructor change and while she still competed, accompanied, and performed she realized that wasn’t her career path. Thankfully by then she had a teacher who supported her in that decision. Ironically she played amazingly well those last two years without any of the pressure on her shoulders.
And she still plays and performs, but she’s graduating college next month with an engineering degree.
OP - your student is young. Support and encourage but be open if the path ends up changing too.
