But no one feels pleasant and positive about content creation when it is not noticed or appreciated (...) but it also requires a strong-minded user to continue publishing and creating content.

I think we all have passed through that feeling, so it means we are still in good mental health and strong-minded, as you say. Although is much better to continue here doing what we like and is valuable content other than spending time in other social media that doesn't pay anything off but mostly wasting our time.

I used to stay late at night or very very early in the morning, but when the body demands you to have a rest, you better listen to it.
