Is it possible to write or create anything original anymore?
Possibly not. I think it is fair to say that we all share the same life root; birth to death. It is the stuff in the middle that is sometimes slightly different. To say we are all unique is not strictly true – love, loneliness, disappointment, illness, parenthood etc. are things we all experience in someway or another – this shared path is what makes us part of the collective human race. It is most probable that anything you write about on the internet will be a shared emotion, concept, or dream and somebody out there will be thinking, ‘I thought of that ages ago’.
The only way forward is to adapt the concept of original thought and simply do things better and write better text and be creative with key words.
