Welcome to Steemit, N8

Thanks for the good introduction. That gets you off to a great start on this platform. And with your experience on YouTube, you'll most likely have plenty to offer here.

Below are a few basic points of advice re posting on Steemit.

1. Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2. Include some photos, images or graphs, to complement the text.
3. Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.
4. Also, if you're planning to upload mostly videos, I'd advise you to also include a fair bit of text, as either intro or background to the content of the vid. Some people (like me) prefer to scan through the text before watching a vid of any length, so see if the vid is worth clicking on.

Hope this helps for now. Good luck, and Full Steem Ahead!
