Hey, Bert: Walking away works for me. Sometimes I don't come back to the song for years. I had two lines:

As I lie here on my bed at night
Tossing and turning, Lord what shall I do

It took me nearly ten years for the rest of the song to come. I was driving in my car one night and remembered the two lines. The rest of the song came out, almost as if I'd already written it but had forgotten some of the words.
