Have you started researching for your new history video before you got sidetracked with the new content? If so, do you think it will be easy for you to get back on track?
the new content is not a "side track" it is the main track. i have written a series of 11 videos/songs of medium/short length to be released in order. then i picked a topic for a research/history video to go after that (did not start writing it yet), then i started making the videos that are lined up.
