First, decide whether you want to specialize, or to be more of a generalist. Read "Refuse to Choose" by Barbara Sher. I am/was a generalist, bouncing from one field of interest to another, so it was electronics, optics, systems, admin and IT, even part of a sales team. Not for everyone. This is called "serial master" in the book. There are methodologies to help decide. Here is a classical one: https://careerservices.fas.harvard.edu/blog/2022/08/28/your-step-by-step-guide-to-choosing-a-career/ https://careerservices.fas.harvard.edu/blog/2022/08/28/your-... But there's no methodology for knowing what field is going to be hot or (importantly) dead in a few years. Things change rapidly. This affects specialists more than generalists. Depending on how focused your interests are, that focus can propel you through tough spells. I learned Unix systems and utilities when not so many did, and that made me really productive. And over time, opened more doors. Others scoffed but I felt the power, and liked it. A business/management career will take a lot more leadership skills on top of the math and computing basics. So will techies as they move "up" the ladder. Understanding some psychology, and especially, persuasion will increase effectiveness over efficiency, so to speak. Good luck.
