How to Make Your Video Go Viral?

We know YouTube is hub for literally billions if not more videos of/for people ranging from very serious to very idiotic and pointless. Yet some videos could have 10,000 views and the same number of followers.  But that all depends on a persons preference and what they like to watch.(1) Well the first step is to have good equipment, or at least a decent kind. (2)A lavalier, although not needed, wouldn't kill you to have and makes the sound quality especially when a person is talking is a great thing to have.  (3)Being comfortable is another big thing when making a video, obviously. (1)Which, in my opinion, is hard to do. Believe me. When I started doing filming for my documentary and I had to talk to the camera in front of the green screen, I was nervous as heck.  I stuttered and stumbled, and I was just plain embarrassed that people in the room would hear me and laugh at something I might have said that they found funny or something like that.  But I was like, "Okay you have to do this otherwise your movie is gonna suck and Miss Licata won't give you a good grade! So suck it up and just do it!" So I took a deep breath and just started talking and after a while, it went pretty easy. I still get nervous in front of the camera but not as much. ....Rant aside....(2) I think this article explains what I am getting at a lot better than I am so go read it. As for my question...iMovie? Really? Ick.
