#1 Take Time Out
However exciting your book is, however compelled you are to write about it day and night, however much you feel it is going to benefit humanity, your community, your pocket, you must, you simply must step back from it occasionally and smell the roses.
Or it will be a painful, protracted and undernourished birth.
Feed on life, feed on smells, tastes and experiences. Feed on balance and enjoyment, push your limits on occasion, see what great work you can produce when your back is against the wall, but take time to feel the wall in the first place!
