Oh well.. If you have a real hobby for videography, then pursue that career, but throughout your teenage years, your ideas of the future do change dramatically. I remember when I wanted to be a builder with my friend, we were planning to run a partnership business etc. - Now I want to be a game designer and game player, both of which I find really fun.
Why a game journalist when you can be.. a game developer yourself? Or both!
Typical YouTube-style mindset, definitely good if you are wanting to pursue a successful YouTube channel, or possibly streaming, whatever you think is easier.
If you have an end goal and a drive, any job in the world could be yours, it just might take a few more years than you hope, but you could easily reach where you want to be with a little sprinkle of hope and dedication.
