Can an Industrial Designer share what their daily job is like?

I want to be an industrial designer but I’m worried I will be limited to making things ‘pretty’ or for marketing purposes to sell more units. I love science and creativity, and the connection between the user and a product. My original goal was to make technology more accesible to people and make people’s lives easier. I originally thought I’d be a designer instead of an engineer because I don’t want to abandon the creative part.

Right now in high school (grade 12) I’m getting high 80s and low 90s in maths and sciences. I like those subjects and am afraid my job will be to just make things ‘pretty’ without worrying much about the underlying technology and how things work. Can someone help me out to really understand what the norm is for an industrial designer? Thanks
