The most important thing is that you gather followers! If you get them it means they like what you post! It takes a while before you make a name. Don't give up!
And I also think that if you post about things you really like people will see that back in your posts as well.
I do post think I really like. The sad thing is I'm making more on this post that I spent 2 minutes on than my post yesterday that I spent hours on.
