I took a computer programming course in high school and really liked coding. I was going to do a comp sci degree, but my dad forced me to do software engineering. In my 2nd last year of uni, I did an internship at a web dev company. They liked me so they asked me to work part time during the year; then after I graduated, I just went from part time to full time. Have been in web dev ever since.
My advice: pick a career that pays well that you’ll enjoy; then look into what you need to get there. Don’t go to post-secondary simply because you like the subject.
I know someone who really liked history, but didn’t think about life after school. Unfortunately, they’re now stuck at home with their parents, working a minimum wage job, paying off insane amounts of student debt. I really wish it worked out better for them, but there’s not many decent paying jobs in that field.
I don’t know much bout any of those places, but I’d think you’d want to lean towards living in a location that matches your skillset, so you can find work more easily. If you’re an accountant, you’d probably want to live near a financial district. If you’re a farmer, you’d probably want to live near a farm. If you have a fully remote job, still find a place in/near a hub for that type of work.
