Business Ideas and How To Get Started?

I'm 17, currently a senior in high-school, and am really thinking about starting an online business of some sort, and I've already watched hundreds of videos on businesses, best and worst ones. I just really wanna start something early on because I've been told that time is the most valuable thing, and I know there is so much money to be made, you just have to seize opportunities, my mom actually has her own small business in psychiatry and it's worked out well for her over the past couple years, and It's made me want to start a business.

My hobbies and some of my skills are, 3d modeling/design/gaming and I enjoy writing quite a bit. I've already invested quite a bit of money into things like stocks, 160$ and I've made 38.41$ profit so that also interests me!

Thanks for any responses!
