IN my opinion, writer's block is the writer's number one opponent. It isn't the censorship committee (if there ever is one), or the ones who are against what you write. It's the lack of ideas or motivations to write.This is why many of us borrow ideas from other articles. Most of the time, we take it from articles that require us to give credit to its authors. There are, however, articles that do not have this requirement. They are called Private Label Rights Articles.
