If you are a person who is slow to say yes to life, or to express yourself openly and spontaneously, try this practice: Each day for a week, find some place to write the word "yes." It might be on the back of envelopes that come in the mail, on the newspaper, at the top of a diary or journal entry, in the dust you find somewhere, on the frost of a windowpane. It doesn't matter where. Get in the habit for seven days to write "yes" wherever you can, and do so with the intention that you will also try to say the word to the challenges that life presents to you.
