CS isn't anymore of coherent subject than, say, math. And (much like math), the useful/practical parts that'll get you 80%-90% there in solving arbitrary practical problems aren't all that difficult to learn. Just learning your data structures and how to implement them will serve you very well for many/most tasks.
