HIE- I decided when I was 12 and never regretted it.
My math teacher back then was very arrogant and he told me and my parents that I would never “make it in life” if I went into anything math related. He also told us that that he would never be able to pass the first actuarial exam.
At that moment I decided I wanted to be an actuary even though I didn’t know what it was. I’m very happy with the decision.
