advice from an author (not me)

I just found this in the latest Author's Guild mag and I love it:

The late Muriel Spark had the following advice on writing novels: "You are writing a letter to a friend. Write privately, not publicly; without fear or timidity, right to the end of the letter, as if it were never going to be published."

Now, I'm not saying I can DO this but I'm sure going to try!

Good luck with your writing everybody.
