Don't be lost! Explore as you can and go ahead whatever u feel good. There are no absolute major that works for all, it depend on what's one's interest. Any major within your field of study work great here. So only thing is what u think, your interest, don't go for a book guidelines. Listen to your heart!!!
 As an civil engg. I am sure u will do better whatever u choose.
Hope this will help!!!!!!!!!!!!!!
