i think what you feel is a natural reaction based on your progression
i also think its important to keep in mind what got you to where you are now: your subscriber base mightve increased, and your views too, but the content youve already uploaded is what lead to that
in my opinion, its important to remember how you managed to accomplish what you have, in order to move forward
to create new content, look to your old videos as a guideline
regardless, the fact of the matter is, ultimately you know what works and doesnt without scrutinizing every detail - we all do, i believe
you know if your content is good enough, or if it isnt
at the heart of it all, we need to ask ourselves: would i watch this? do i personally think this is good enough?
if the answer is yes, even though the video might not be perfect, or even far from it, you should publish it
just some thoughts my friend
