Interact with people who know how to do it. If there is a local college where you can take some courses see if you can find one on writing skills? Sounds like you want comedy skills, one of the best things is to find a group of people working on improv comedy and that will get your ideas critiqued. Frequently these groups are not professional, just a bunch of like minded people sharing. As far as YouTube videos, get people to honestly critique what you are doing.
