Great post, thankyou for putting in the time to put it up.
There's also the flip side, even if the content creator is doing it for fun and not having these unrealistic expections there are unrealistic expectations from obnoxious friends.
I've had a friend tell me my channel was crap because no one was watching my videos, after only two months of starting my channel. He immediately showed me a channel which had 55,000 subs and said I had to make videos in the same style as that channel. That channel had been around for over 5 years.
At that point I had already 200 subs and was averaging 200 views per video.
He expected instant overnight success. He's a good friend of mine, but has given zero support in regards to the channel.
