As you should know, steemit is a platform in which you can post, coment, and vote to earn money. So, what you have to do here, is to write thoughtful, interesting, and catchy blogs; in that way, you will achieve more followers, who can help you to increase your popularity in the platform.

On the other hand, I would recommend you to look for post that may help you to start posting in steemit. Thus, it is important that you can talk about something you consider yourself an expert, so people could feel identified with your wirting.

Start writing a "introduce yourself" in that post, write about you, for example, what you like doing, what you do for living, and so on. Do your best, and try to write good material for the community!
