Update when you have a video that isn't one that explains what your videos will be.
Do it like other youtubers like Pewdiepie.Scream all the time. Have an overly long musical intro. Play horror games for that scream factor. Play minecraft and act like a doofus.
you have a great voice for doing pc tutorials lmao
Do what you do, follow the Youtube rules and don't make a video making yourself look stupid.
