What are some good careers to look into?

TLDR: Looking for advice on where to look for a good white collar/marketing/freelance career. Not against learning new skills or going to school, just want some avenues to look into.

I graduated from high school last year and am currently working as an electrical apprentice. I mostly chose it so I didn't have to stress about school, but it really isn't what I want to do. I don't fit it with any of the people I work around, have my fair share of body pain already due to sports and even more from working, and have always been more interested in a white collar, tech, and marketing type jobs.

I learned what application deadlines were pretty close to them and my dad was putting pressure on me for not having already decided on something so I just chose a trade so it could be over with, but now that I have my life more under control (managing my money properly, healthier lifestyle), I'd like to start working towards a different job that's more on the books, I'm just not really sure where to start.

I plan on staying at my current job for a while longer and build up some savings, but I figured in my free time I could learn or take steps towards a different career.

I have mid B's to low A's for most of my grades, though I could upgrade if needed. My primary goal is some sort of freelance work or a personal business, but I'm interested in marketing and managerial work as well. Any advice on where to start would be appreciated.

Thanks!
