Hello Florae, and Welcome to Steemit.

As you implied in your intro, it does take quite a bit of time to learn the inner workings of this platform. But the best way to do so is to start creating some quality-content posts and then uploading them.

You apparently have a range of interests, so find something that you want to write about, and start creating some fine content.

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.

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