Honestly I kinda stumbled into my specific career. I've known I enjoy working with computers for a while, so I took digital tech class all through high school. I went to uni thinking I'd do mechatronics engineering, but that needs chemistry so fuck that. I then switched to software engineering, but then I saw the timetable of some second year engineering friends I had, then said fuck that. Then I switched to computer science for the next year, planning to go into researching ai (this was in 2020, don't judge too hard), but dropped out for my mental health. Then a family friend at my church offered me a position doing automation/efficiency programming, which was better than the pool attendant job I had at the time. I've been there since.
Also, if you're not sure what to do, don't feel guilty about taking a gap year. Take that year, earn some money, figure out what you enjoy doing. And don't feel like you have to go to uni. Polytech and trades are just as good as uni.
