Advice 1: Programming worths it.
As someone with extensive experience in both mathematics and programming, I recognize the importance of both skill sets. In the future, while solid math skills will always be important, the ability to master programming skills will produce tremendous opportunities and be very helpful.
Mastering the basics of c++, which will allow you to write your own projects, takes only 30 hours, while mastering basic math will take significantly longer. Why not consider programming?
