At look at your current post's earnings? Do not lose confidence. I am also nat that good in english. That is the reason I joined a blogging community. To enhance my english skills. You should be happy that you are trying to enhance something, a part, in you. Also, I am a newbie too. But one thing I learned from my almost three months steemit experience are the following: (a) post more quality content posts, (b) comment and comment, quality comments of course, (c) start a contest, if you can. This will help you gain more sbds. Although it's not just sbd but experience also that counts. See you around.
