Programming Related Jobs

I am relatively new to programming through all criteria's and am still trying to find my direction through it. Since I am only in high school(not graduating yet) I am a very curious and passionate "developer". I spend a majority of my time coding and get side-tracked with different projects that are failed attempts. Multi-tasking is a major problem for me. I always just through different projects including vision tracking, web development, software development, and mobile development. It's depressing because I can never finish and project, find very little documentation, and am always learning the syntax to different languages. After I learn the syntax, I try to jump into different frameworks or sdk's but don't understand what I'm doing. Does anyone have any idea of what I should do? Any response or input is greatly appreciated and thank you for reading my post.
