What do you think my mom means by this?

im majoring in economics. sometimes I mention financial analyst jobs (after graduation and 3, 4 years of experience). she always says "yeah, but those jobs are hard." does she think I'm not smart enough, or this is just something I'm sensitive of? my mom is more interested in science; when I talk about econ she doesnt care but she loves my bio class. I just want to make my mom prooud; because it makes ME happy; then that makes my grades better. She said I could do genetic counseling. What do u guys think? Should I change my major to a minor, and talk to a school counselor about genetic couseling? i'm 20.
