How did you figure out international law was the pathway you wanted to explore?

I plan on studying Political Science in college; however, I am unsure on what I should minor in. In the future I would love to work with spanish speaking countries, so I thought maybe a spanish minor would be perfect. I am bilingual, but I believe my grammar skills could improve immensely. On the other hand, I've also heard that sociology is another minor that is extremely helpful in understanding how people act the way they do. Lastly, a minor in international- affairs/relations would be beneficial in the way that I do plan on working internationally eventually.
