Hi, Omar, and welcome to Steemit.

With your varied background, you might be able to bring some interesting perspectives to Steemit. And as a writer, I can say that your command of the English language is excellent, so that will also help you as you develop your blog on this platform.

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!

p.s. You made me hungry for some Mexican food.... :-P
