That it's ok to be a bit varied but not to film anything and everything just for the experience because no-one will know what my channel is about.
To watch and learn from people like Derral, Roberto et el sooner, their advice would have helped me more than watching dozens of other popular, big creators that I wanted to be like.
Not to be so naive when it comes to other people's intentions, 'let's support each other' or 'we should be YouTuber friends' are basically just fancy ways of saying sub4sub.
That's it's good to have an interest in my analytics, but not to obsess about them to the point I am checking multiple times in the middle of the night.
To make videos that I enjoy, not videos I think people will like.
