Hey man! My intention was not to teach or hurt anybody. How many videos are okay depends only on you. I was just sharing my honest opinion from the point of a viewer who really gets overwhelmed when I wasn't for example some days on a channel and there are like 10+ videos to watch. I instantly feel like having no motivation from the beginning.
And of course talking about those limited capacities to make people just think about it. What they do with this information depends also on them.
Just keep doing what you love to do and don't let yourself dictate by other people. Even not by videos like this one ;)
