Tried with so many Businesses - cannot get the right one!

Hello, I am 17 years old, I started my journey with making money this summer. I saw a lot of businesses, a lot of chances but didn't really stick to one. I cannot decide which to stick fully because whenever I start a business or side income or anything I just get better idea or see someone else doing something easier and better and then I go in two different fields and end up with none. Now I bought a course about n8n and I am going good but I saw there is really easy money with making content and doing affiliate marketing or making videos for brands or SMMA or to start reselling so if someone can help me how to decide, what to decide I will be so grateful!
