I want to be a good content writer. Until now, I've only made $80 or something. My chances of success are really low. If there's a potential client and he asks for some samples, there's a 50% chance that he'll reject me because he doesn't need the kind of content I write. So that's why I need some tips. How exactly do you write? What are some general tips? Some mistakes to avoid? What sells? What sort of writing are clients these days looking for?
