Welcome! You have to create something that stands out and get followers. I think the best advice is write about things you really care about. Don't copy and paste, put some effort into it. If you're posts are good reads you can earn some decent money.

Also check out different tutorial posts by experienced and successful steemians, e.g. papa-pepper. He did a whole series with tips for newbies.

Have a good time here!
Cheers
