Hey Yana, I'm rooting for you.
However, as you know, I think Medium (and other writing platforms) are the foundation but you have to add video content.
That's the biggest hurdle to overcome. To show yourself on camera OR of course start a faceless channel (#1 trending topic here on Medium for all introverts. haha).
At the moment YouTube and TikTok are the best.
IG is a dark hole. I used to be an influencer there, but would NEVER EVER do it again.
I think your USP is that you have a LOT of raving fans that are rooting for you.
