Hi, sorry for the late reply.
I've always been interested in math, but when I was a kid I wasn't encouraged to do well in it. I took some advanced classes but didn't do much in them.
As a kid, I was pushed to become a nurse, teacher, or social worker. All of the women in my family have these types of careers. According to my family, there was no need for me to become a scientist/mathematician/physician.
It wasn't until I decided that I wanted to pursue a MD/PhD that I figured I had to change my mindset. I stopped seeing myself as someone who couldn't do it and as someone who can.
Women in science need mentors, people who can encourage them to go for it. And plus, it's never too late to go back to school. I met someone the other night who's working on a PhD and he's in his mid 40's. And I read about a woman finishing a PhD at MIT when she was 46.
Are you interested in science?
