Thinking about going back to higher education part time, what path would suit me more?

Hi,

So I graduated this september with a graphic design bachelor specialised in 3D, one of the most thorough and versatile degree in this field from Belgium.

However as you know this field is very much cooked, so I traveled a bit and ended up in Warsaw with a pretty good job at an international company.

However I've been thinking about continuing my education, in something else entirely. I'm thinking about doing part time studies.

I am interested in everything international, looking at how nations interact with each others, the politics and economic of countries... I am also very social, I am an extrovert and I hate repetitive work.

I think I would like a specialized field, with hard and soft skills that are timeless and valuable, for exemple you'll always need people in healthcare right.

I'm thinking about international political economy, IR, international business and economics.

Do you guys have any tips on what would fit me more?
