Uh, what question? The previous one? The one about second thoughts about majoring in math? I have talked to people who were in high school who were about to go to college. I'm not sure if I specifically talked to them about math, but I told them, among other things, to make sure they had a clear idea of why they were going to college, and if it was because they wanted to prepare for a specific career, they should make sure they were going the right degree(s) for that field. I've told people many times that I learned after I'd taken many math classes that you can hardly work as a mathematician without a PhD in math. I've told many people that I've learned that a BA/BS in math is useless without another degree to go with it.
If someone in calculus 1 asked me if they should major in math, i would ask them if they want to be a teacher or get a PhD or be an actuary or do a double major. I would tell them not to major in math otherwise. I'm doing it now with the intention of also getting other qualifications at some point.
