The good news is that you have plenty of time to decide what your career should be. Expect that you may change you mind several times. Certainly, everyone that responded has given great advice. Math is a general subject, so identifying what branch or branches of math interests you most is important. Based on whatever you specialize in, should narrow down your career objectives. Take the time you have to find what math you are passionate about;
Matrix Algebra - Engineer
Numerical Analysis - Data Analytics, Risk Assessment
Operations Research - Operational Research, Data mining
Complex Numbers - Engineer, Statistician, Physicist
Calculus - Economist, Computer Animation and Game Development
Set Theory - Architecture, Operations
Game Theory - Game design
Analysis - Forensics
As it was mentioned before, a rewarding career as a teacher or professor
Best of luck to you.
- Biology (Biostatistics, Epidemiology)
- Data (science, analytics, engineering)
- Machine Learning
- Many more!

I think the most important thing to keep in mind is to understand if your interest in math is for the challenge of the problems or for the actual subject, but all careers have such challenges.
Hope I could help.
Good luck for your future^^
