First, do you have a semi popular YouTube channel already? Because if not why would you want to go full time for? Secondly you are 10 and need your education. People don’t realise a lot of decent YouTubers studied media and the like before becoming famous. Start as a hobby and if it becomes popular then put more time into it but finish your education too because it will help you in the long run.

To add, you are too young for Reddit.
