Beginning? Quality, DON'T FOCUS ON!
Focus more on Quantity, and I say that because No one is going to watch your first videos and youtube only really starts suggesting around 50-100 videos in... And naturally as you grow so will in editing skills. So no matter how good your content is today, later down the line you will look back and see things you could of changed to make it more interesting or engaging. Just get started, posting, brainstorming, and finding yourself in what ever niche you choose.
Also its interesting that on youtube and other platforms how they choose sometimes to boost views on the content I placed very little time and effort on, its laughable and annoying lol... Almost as if they prefer natural content over edited. Im just saying, get started, learn keywords and search related topics and just go!
