My primary piece of advice to college students who are computer science majors is this: double major.
Computer science is great for understanding how computers work, programming, and learning the theory of computation. But where it really matters is how you apply those principles to real world problems that exist outside the computer science field.
If you double major, you’ll be exposed to a different discipline and begin to understand its problems. Hopefully down the road you can use your computer science knowledge to create solutions to those problems and produce real value in that field.
That’s my 2 cents for college computer science majors coming from someone who’s far enough outside of school to have some perspective on how you can produce value.
