I know this is very selfish and probably I know less about your life than you do but...

Why not just make ~5 minute YouTube videos as your primary work? I know you like making music too but it seems like the money and popularity show that your video work is the use of your time that people think is the most awesome. if your next video is similarly popular to the Japan video would you consider making those types of videos your primary focus?
that reminds me of when everyone thought i was wasting my time trying to make a long history video about japan, when i was already perfectly popular on vine
