You gotta start somewhere. Look around Youtube for inspiration. Whether it would be ways to edit or their style of vlogging. Sometimes, software has its limitations, but once you get a direction or theme for your videos, you'll know whether you need the software or not.
I'm not a Youtuber, so I don't really have an audience or following to have to explain what's going on. So, I personally do not like narrating or just sitting in front of the camera explaining the image. I like to let the video narrate itself.
Here's one I made a few days ago if you want to get some ideas.
I think this is one of my better edits I made a month ago.
I like to use pictures to change up the pace of the video and if your camera has a time lapse function, that's also a good way to change things up.
@Raintoons could also chime in here.
