Omar Zenhom argues that every creative work, from plays to YouTube videos, needs a great script first. If your title promises to teach how to start a YouTube channel, your script has to actually deliver that by the end.
Anything starts with a great script. Any good play, any good movie, any good show, any good song starts with a great script, with great words, with what you're communicating as much as possible. I dedicate myself to having a script that's tight, that is natural, but also delivers on the promise, which is the title of your talk. Whatever your title of your talk is, that's the promise to your audience. I want to make sure that by the end of my script that I fulfill that promise. If that title is how to start a YouTube channel, and at the end of the talk, people don't know how to start a YouTube channel, then I didn't deliver on my promise. I want to make sure the script delivers.
