I tend to use a lot of plr articles, and will spend the time to rewrite them into my own words. Sometimes I will also research the topic and read the content outload and put it into a video to make it unique in that fashion.
There are places that provide free content that can be reused, and sometimes that helps me to come up with plenty of new title, and topics to create more information about the niche I happen to be working on for that weeks project.
I love to write, so words most times come naturally for me, or I will look at an article, and think to myself, hmmm I think the viewer would like to know more about this certain topic, and I then will create questions, and find the answers and blend that also into the articles.
Hope my suggestions helps with your question
