Hey Mickey! Welcome to Steemit! So nice you decided to join :)
In the beginning everything can be a bit overwhelming. But don't worry you'll get used to it. Don't get frustrated, but just be you and share what you love!

Here are two articles (not mine) that really helped me find my way on Steemit:

https://steemit.com/howto/@scrooger/how-to-post-with-html-markdown-super-simple-with-copy-paste-cheat-sheet-make-your-posts-looks-so-much-better

Enjoy!
