In Rob Brezsny’s Astrology Newsletter he shares an exercise…

“I invite you to write down brief descriptions of the five most pleasurable
you’ve ever experienced in your life. Let your imagination dwell
lovingly on these memories for, say, 20 minutes. And keep them close to
the surface of your awareness in the next three days.

“If you ever catch yourself slipping into a negative train of thought,
interrupt it immediately and compel yourself to fantasize about those
Five Big Ecstatic Moments.”

You may want to check out Rob’s Freewill Astrology, too. I find his forecasts to be sometimes puzzling, sometimes dead accurate, and always fun and stimulating no matter what.
