Category theory is also very relevant to programming. But, curiously enough, learning and practicing programming is probably a better intro to eventually get to category theory, than the more usual approaches mathematicians take.
Discrete math is lots of fun, but less applicable to the kind of glue code many people write most often.
(Category theory is in some sense exactly the theory of glue code. But it's also generalised abstract nonsense.)
