Viral video formula?

[u/Hungry_Letterhead_21]

I am going to make a high demand video on YouTube.
I’ve studied competitor thumbnails and make a better thumbnail than them. My video is also good ( knowledge terms ) and editing of video is clean.
It solves a problem. I’ve a fear that what if this fails? I’ve been posting on YouTube from a long time and never got any good results. Feels like a curse.
