To be a professional at something it takes about 5 years of doing it or 10000 hours. Let's say it takes 10 hours to create a video, so to create a good content it will take about 1000 videos and then you can say that you have generated a good content. Before that it will acceptable, but you have to know that Rome is not a build for a day. - It takes time to be good a something. So just creating as many as possible and in time the content will be improved from the feedback of your viewers. Be prepared to hear some hateful comments, but don't mind them they are just envy that they cannot do what you do.
