Study engineering and / or mathematics. I have degrees in both. I work in software and hardware engineering. Amusingly my job results in replacing people (like cashiers and security guards) with automation systems. Appart from a few meetings and occasional presentations, most of my time is spent with a small team.
Most of the work is alone, we analyse entire systems, break them down into sections and develop custom hardware and software processes to automate the systems.
The latest thing I'm working on is a facilities management system for a major health club chain. I've been there for 2.5 years I earn £38,000 (~US$80,000). Without the degrees I'd be earning £24,000 max, probably more like £18k.
Plus most people who study electrical engineering and mathematics are quiet, nerdy, friendly, probaby have SA (I do).
