Truly in sync with my post, and what you are proposing here is exactly what I have been doing a few weeks ago.

I already have some experience with camera and watching myself, because I was in a theater group many years ago, so I increasingly got a feel for it. Nonetheless, just for fun I decided to make videos talking about spiritual stuff some weeks ago over several days simply to refresh the feel of watching myself anew, and I did exactly what you said here. Perhaps I will make some DTube videos one day, but for now I enjoy writing.

Very good that you focus on the term self-love because ultimately it is about being authentically comfortable with oneself, not what others think of you. Some people on camera might draw their "confidence" from positive feedback by others, not from positive feedback from within. Does that matter? I think so, because when we draw our entire confidence from what others think of us, this might easily affect us in the other direction as well. It is similar with photos. Personally, no matter how nice the feedback given by other people was, whether honest or not, it wouldn't make me like that particular image more. If I don't like it, I don't like it. The same goes the other way around. If I like it and others not, I would still use it.

And that is the main point I guess. Do I truly love myself the way I am irrespective of what others think of me or will I make my self-Love dependent on how others perceive and receive me? Only with the former the self-Love can be authentic, while with the latter false bravado, as you call it, is most likely, and that is the huge majority of people these days.
