You're aware that you have the power to actually do this, right? You can't change where the planets were at the moment of your first breath, but these positions are only indicators of the real forces at work. The "astrological forces" are living and dynamic within an individual. You can act on any part of your chart you choose, or you could decide to open a completely new branch of development and act like someone your chart could never predict. In short, you are your "chart." That doesn't mean that the chart controls you. It means that you, as a conscious life form, control the expression of your chart!
