What do you guys think?

In the second term of the 2nd year at University, Mum says the course I’m currently doing (music-related) is pretty much useless. Almost no useful effect to humanity whatsoever. She thinks I only chose it because it was an easy course to do. The real reason I chose it was because not only it’s my passion but it is because there is a strong part of me that truly believes it will have more of a huge impact to people in the future. So to hear my own mum say this kind was a pretty huge punch-to-the-gut because then I’m left feeling misunderstood. She thinks I chose it just for the fun of it when really through my passion I want to be able to use the knowledge I have, the ability I have to not only be successful but to also help people along the way. But whenever she says this I don’t talk back because I never wanted to start arguments and I knew my mum was currently undergoing stress from her university experience so considering that I just didn’t say anything. Any advice? Thoughts?
