This here article link also neatly links to my approach to writing. The source of creativity is often associated with wild emotional states, as though you have to tear yourself apart and use the bits to paint something dramatic. Peacefulness is seen as static and therefore unproductive, but the calmer I get, the easier the words and the meanings flow. Experience of life's dramas helps understanding but it needn't, it shouldn't, become an addiction.
Read and learn; peace out! xx
