Hello,
The thing is that you think a lot and try to analyse everything before its even done. It’s good to be practical but not try not over analyze.
However you need to set a clear goal whether you want to be a YouTuber or an astrophysicist. Just put your originality into your career.
Please do it and work for it, do not get confused and try not to do multiple things at a time. MAKE A GOAL and WORK ON IT.
