Hello and welcome to this awesome community! It's good to have you here.
Don't worry I also never was a blogger when I came to Steemit about two weeks ago. And I also didn't have concrete plans about specific topics.
What's most important is that you're authentic and love what you're doing. I hope you'll have a wonderful time out here.
If you would also like to post in German, the German community is very strong. Content can be found easily by looking out for #deutsch. If you have any further questions I'm always willing to help.

Grüße vom Bodensee :)
