We can change our lives from changing our thoughts. In Astrology the planet Mercury rules the mind and determines how we think. As there are twelve zodiac signs there are twelve styles of thinking. For example, people who were born with Mercury in Capricorn have a very conservative way of thinking in comparison to people who were born with Mercury in Aquarius. Those with Mercury in Aquarius are very innovative and forward thinkers. To know how you think astrologically, helps pinpoint your positive and negative traits. Therefore astrologers would be quite helpful in ascertaining what affirmations are needed to say on a daily basis. This in turn helps start the change that is needed from a negative mindset to a positive one.
