I've honestly found utility in courses I took across the gamut in terms of geophysics vs. geochemistry vs. planetary science vs. computer science. It's probably no surprise that, being in the oil & gas industry, I do lean more heavily on skills from the geophysics, geofluids, and computing courses. But I think the best preparation I received from my EAS education is diversity: of thought and culture. I learned effective approaches for problem solving and critical thinking, and that rote memorization isn't adequate for addressing many real questions. Also, EAS consists of and embraces a melting pot of cultures and ideologies - which is what a thriving global community looks like. Exposure to cultural diversity via EAS was a tremendous help towards growth of perspective and understanding
