Future Learning

I plan on becoming a Civil Engineer when I graduate from college. Right now I can't say exactly what sub-field I wish to purse in Civil Engineering possibly Structural engineering or Transportation engineering, but either way I'll probably be content with whatever choice I choose in the future. After all I chose Civil Engineering for how applicable of a subject it is, it can branch off into different subjects such as economics, logistics, urban planning, other types of Engineering, Surveying, Physics, and Mathematics all of which are subjects that I am interested in. I don't have a definite plan on what I want to do in the future as I prefer to be flexible enough so I can change my career path to fit what I wish to do in the future.
