I can definitely relate to this. Here's how you do it.
You just do it. Period.
If you have two videos ready, make them public. It's the intention that counts. If you want to help people learn, or contribute, don't get bogged down by how people will judge you. It is an extremely exhilarating feeling when someone reaches out to you and lets you know that they found your content useful. The moment you make the switch from being a passive consumer to an active producer, something switches within you.
I started putting out videos on tensorflow a few months ago. https://www.youtube.com/watch?v=g-EvyKpZjmQ
This was the first time I had done anything like this- my goal is not to get subscribers, or views or anything, it is just to put out content in a form that I would have liked to consume.
I have a three and half year old and there have been times where he is literally sitting on my head while I am trying to make the videos. It's all worth it.
Just take the next step.
