You could go into the business world, you could teach English abroad - get paid and travel. The solar industry is growing in a lot of states not sure about UK or Canada. Marijuana industry might be a good idea^(?) I am pretty sure this is against sub-rules but https://www.hist.cam.ac.uk/undergraduate/hist-tripos/info-all-years/skills has some useful info to your first question. I personally started working at a school, focused on SPED then went back to school for education. Be warned (if you forgot secondary school as I did) that a lot of History at the secondary level feels boring after college IMO very surface level and taught very single-narrative textbook. Good luck with your journey.

I majored in history without any thought to what career plans would be afterwards. I figured I’d work for the government or go into academia.

It turns out the research, writing, critical thinking, information synthesis skills you develop through the course of a history degree translate very well to the corporate world. I was able to land a job at a corporate research firm (market research), and from there I continued expanding my skill set to work in product, strategy, and marketing functions.

I would also recommend that you continue developing other skills that would complement the ones developed in history coursework. Survey research/analysis, data analysis/science, and interview research skills are good places to start.

Why did you major in history?

The research, writing, and analytical skills one hones in history degree curricula is translatable to a lot of different professions. I work in university admissions and those skills are the things that have made me stand out among my peers. I've become the go-to person in the office (I'm the only one with a humanities background) for doing data analysis and writing reports at the end of each admissions cycle.

I work in tech, for a publicly-traded company. I majored in ethnomusicology and my team includes a theater design major and an MA in Divinity.

Liberal Arts majors are fantastic for businesses. Show them you can write well, know how to do your research and see the bigger picture. I'd advise you to do two things: first, take the Strengthsfinder quiz and evaluate the way your brain works. Think about what kind of roles that suits you for.
