I recommend adding AT LEAST 5 more lectures that are new. If your goal is to turn a lot of your content/videos into a paid Course, that's smart! Because you have a head start on that Course creation process.

That said, you want to make sure you're giving good value if you're charging for a Course and that a large number of those videos CAN'T be found elsewhere for free. It's okay if some of them are, but don't go overboard.

Hope that helps!
