There's an old adage in writing: 'Don't tell, but show.' Writing is not psychology. We do not talk 'about' feelings. Instead the writer feels and through her words awakens those feelings in the reader. The writer takes the reader's hand and guides him through the valley of sorrow and joy without ever having to mention those words.
Natalie GoldbergLet's say I've directed that [writing] energy into writing my latest book but suddenly, I really want to write about an onion. I don't say to myself, "No, you have stay on the subject," because I know that the longer I stay on the subject the more boring I get. So, if my mind wants to write about an onion, it might be a deeper way to go into what I'm working on, even though it might seem irrelevant. This is how I've learned to follow my mind.
