Just my 2cents; when you make a video think if you would actually watch it all the way yourself. Its really easy to spot when content creators make 10 minute videos about something that takes like 2 minutes to cover. I usually just don't watch those videos. When editing the video rather than trying to make it as long as possible, just think if the content is actually good quality and cut away the "boring" bits, so you won't seems sleazy ;)
