Welcome to Steemit, Stas. I'll tell you my opinion about school, though I'm not sure how pleased your parents would be if they read it. My opinion is, get out of school as soon as possible. Of course, it'll be easier to convince your parents to let you leave school if you're already making some money... Video blogging could be a good opportunity for you, especially combined with Steemit.

The other thing is, don't spend too much time planning your project. Many people spend too much time planning and never actually start. Best to start as soon as you can, and change your approach as you go.

Good luck and have a good one.
