This will be a long comment get ready!
Let me greet you too in this awesome platform! You will soon realize that this community is way different than facebook, instagram and other social media as everyone is helpful to each other, so don't hesitate to ask for help or to ask questions!
This is my second post I and I am not sure about my concept at Steemit.
Don't worry just experiment and see what you like! For example when i started out i had no clue as to what i should write and i did the most simple thing! i wrote some review of movies/series/anime i have seen or currently watching. Then i experimented on other concept and nowadays i just write whatever i feel like to :P (so don't bother!)
We also have some things in common, we are of the same age and even our names are similar :P Yours is Angelina, mine is Aggelos or (Angelos) haha!
The key for success in Steemit is interaction, that means to reply back in the comments, make comments in other people's posts and form relationships with the members in here. That will allow you to gain some loyal followers and even actual friends
