Don't stress too much on the "making it good". Be yourself and write about things you care. You will find your audience.

In German community there's someone posting almost daily about his job and society. Seldom any pictures, no dividers/headers or anything. But he got his readers and corresponging likes.

Recently I came across a nice quote reading a book. "If everyone likes you, noone takes you serious"

Don't force yourself to post. Write because you want to. And then just write.
