The secrets to growing here is

• Interacting (upvote, curate and resteem when need be) like you doing already.

• Be creative with your posts.

• Avoid plagiarism, credit both images and quotes sources

• Use the right tags on your posts to gain the right audience. (Use nigeria and africa tags on all ur post to enable Africa and Nigeria communities read your posts)

• Be creative with your posts, use the right paragraph and puntuactions.

And most of all, just act like steemit is a normal social network like facebook, instagram etc where you only post to express your views and also to meet new people, earning on steemit should be a secondary thing like an added advantage.
Do the right thing and act like nobody is seeing you.
