Awesome man! What I have learned is that sometimes you just do the video for yourself and what I mean by that is, like you said you are just trying to get comfortable talking on camera and the more you do it the better you will feel and sound! So just keep pumping those videos out no matter what! Sometimes you might only have a few views on them but what matters is that consistency of you posting will set a standard for you and it will help to keep your channel looking active for google analytics.
Keep them coming!
