The discussion on self-esteem / confidence is a pretty big deal IMO.
It’s easy to say, I don’t have anything insightful to talk about, and it’s probably likely that you aren’t a real expert on something. The thing is, as a viewer I go in with that understanding. I think so may people believe ‘I don’t know enough to make videos about XYZ’ that they automatically assume that the person who is making those videos has more knowledge then they do - and this does not have to be true.
Everyone has insights, and as a viewer I know that you might be wrong, and that is OK.
People are watching these videos because you are putting yourself out there, not because your insights are greater than theirs but because they enjoy the conversation. It’s just like on this message board. We don’t know shit about promoting a web series, just look at our view counts! (lol) but we talk about it all the time. It is a pursuit of knowledge, and in that sense, right or wrong, discussing, reading, watching is always helpful.
