Choosing between two very different majors! Help!

In the coming months I’ll be going off to college, yet I still can’t decide what I want to study.

A little background: I’ve always been an A student. I study well and never had problems in any course. In high school I excelled in both scientific and humanities courses, and I’m having a hard time choosing between Civil Engineering and an Economics/International Affairs double major. I’ve taken both economics and physics all through high school as well as advanced math courses. Physics interests me and I feel like engineering would always be interesting because I enjoy hands on work and projects.I am also always curious about structures and the work that goes into building and designing. But I am also very interested in International politics and the economy (how politics affects society, how refugees effect countries, how to help refugees, etc…). I did Model UN and a summer International Relations camp and loved both because I’m quite a social person who enjoys expressing opinions and speaking in front of others, and I’m afraid the engineering field would leave me without that excitement. My dad is a successful engineer with his own company and he loves it, but he pushes me to study whatever I want to.

ANY suggestions or insight into both fields would be greatly appreciated. I want to know which of these would be more realistic/useful to study for the future. Thanks!
