How to start a YouTube channel?

[coy]

I know how to sign up, I have made one before, but I didn't have many good videos, and I closed it, but I don't remember why I closed it, I just did, but I have MUCH better ideas now for videos. The thing is, I'm not sure what videos to start it off with. My ideas that my friends and I agree with are ...

-My coming out story (I am gay, it it was hilarious what happened, but long story)
-Speed hair dye (I am dyeing my hair soon, so like a video with music in the back, camera audio taken out, and I'd speed it up, just for entertainment)
-Daily vlogs (Not sure how to make a first one, but I know how to continue, I'd use my phone)
-Home made anti-bullying ad (Me and my friends run an anti-bullying group on Facebook and we were thinking maybe that would get a lot of views and I could continue with an audience with them)

Any of those a good one to start off with?
