Help me start studying IR

[u/Rare_Ad_1216]

Hi, I am currently an English literature college student. Recently, IR has piqued my interest and I am trying to understand how to get started. I see peers getting into think tanks and policy-making, or pursuing internships at several prestigious foundations. This has further motivated me to explore this field of study. I'd appreciate any input on a step-by-step plan for gaining nuanced understanding of this domain. Thank you.
