At first, I was quite hesitant about letting those around me know about my channel because I thought they wouldn't "get it" or they'd know more about me than I was comfortable with. But as I've grown, Ive realized that I'm proud of my channel and if I can feel comfortable with complete strangers watching my videos, why not people I actually know?
Not everyone is going to get it, not everyone is going to support it, but some people will. I still get nervous about sharing my content on my social media and don't do it often, but I wouldn't go out of my way to hide the fact that I make videos, and I find myself sharing it with others who I think may be interested in the content that I upload.
