I remember a Prof telling the class, somewhere around my senior year in engineering, "Your degree means you know what books to look in."
I took advanced calculus, nuclear physics, and nuclear reactor design as electives. I never had a job where these were really necessary as part of the job. They have, from time to time, helped me to understand "the issues" in political discussions.
What I learned from courses in chemistry, internal-combustion engine design, metallurgy, and machine design helped my amateur sports car racing.
I started out with a Mechanical Engr degree; worked at Chevrolet Test Lab. One year later, went to work for the City of Austin, Tx, Elec Dept, learning the overhead distribution system--and cable TV installation needs. After a little over a year, I wound up becoming a civil engineer, becoming pretty knowledgeable about dams and reservoirs, canals and pump stations, and pipeline construction with the Texas Water Development Board--11 years' worth.
The point of all this is that you never know how life itsownself is gonna turn out. You'll never know what part of your education will be the most helpful. I agree with the advice above about a well-rounded general education, with extra emphasis on computers and maybe some business courses.
Regardless, I think young folks today have far more opportunities and good choices than ever before in the history of the world. It seems like everytime I turn around, I see something else where I could have fun making money. Opportunities everywhere! You're only limited by your imagination and your "get up and get after it".
Best luck!
