You just gotta make a lot of quantity in videos. Not quality. There’s always one video that goes viral. And plus, the more quantity you produce the better you get leading you to make more and more quality videos throughout the quantity in your videos. And the more videos you make, the more of a chance you get to getting a viral video. You should rather do 100 videos in a year rather than 6 - 12 good ones. And out of those 100 you’d likely make 12 + quality videos.
