When you say you want to get into politics, what exactly would you ultimately like to do? Run for public office of some sort? Because other than that (which you really can’t do successfully until you’ve built some sort of successful career and life and track record of your own), what is it that’s really of interest to you in the political realm?
Be a congressional clerk or something? Not a long-term career path.
Be a lobbyist? Well, (1.) you need political and business connections (i.e. need to have a career first) to do that and (2.) you might not respect yourself in the morning.
Ultimately be a cabinet member, or at least mid-level policy maker in the State Dept., Defense Dept., etc.? You really need to build a career based on expertise in the underlying relevant subject matter in order to do that.
In other words, get graduate degrees (maybe multiple ones) in foreign studies, or the study of a particular country or region (Russia, China, Middle East, Islam, etc.), or in defense policy, or in international trade, etc., etc., etc.
I’m not trying to give you a hard time, just trying to say that you should try to flesh out exactly what you might want to do when you say you want to get into “politics.”
Hope that helps.
