The rate of change can be only minute day to day or drastic due to a traumatic event. This change can be very threatening to the conscious ego and it will strive to maintain that which is known and controllable. Some watch their daily Sun sign horoscope or, if they have studied a bit, watch their personal transits. You can't stop change by ignoring it, or by having some idea of how the future will be from the present. We must realize that future isn't - until it is the present, otherwise we are never living in the moment.
All astrologers have clients who want their future foretold.
Today's astrologers want more meaning in their professional lives than being a soothsayer. They are seeking answers to the why of events, the why of life. We all have come to crossroads in our lives and made decisions that have changed our lives. Making a prediction gives no choice and ignores all options. They use the metaphor about being in a boat on a river.
