I think it's incredible what Marina has been able to do here on YouTube.
She has been able to create a massive subscribers base on multiple channels in a very reliable way, and in a short amount of time. That is just so rare to be able to see someone build one channel, let alone multiple. And, I think that goes to show that she has been able to figure out how this system works, and how to make crucial decisions to be able to reproduce these results over and over again. She has got the check records, and she definitely knows what she is talking about.
And, what is more about Marina, I think she is able to articulate things and to distill information in a way that's valuable, and not just to people who are already building super big channels.
She has been able to synthesize what she has learned in a way that is super helpful for you.
So, I don't know what else to say except she is the best of the best.
