OK, ok.....  In brief - just one of the reasons why the time of birth is so important is to dictate the shape of the chart.  Without digging it out I can't verify this, but I know from personal experience over three decades of doing horoscopes that if the majority of planets in a chart are on the left, then the person is dedicated more to free will, choice and self determination, and if they are on the right then the principle is primarily fate, destiny and pre determination.  Similarly, if the planets are predominantly above the horizon, then the person experiences directly and becomes more outgoing, whilst if they are in the bottom of the chart then the person assimilates and ponders and becomes more internalised.  And if the planets in your chart are all over the place, try looking at life as though you have many lessons instead of just a few.  The sign and house position of the planets is the window dressing, it is the angles they make to each other that determine characteristics, whether individual or generational.  Remember though, that every single person/chart is unique and different and can never be replicated, so individual experiences will always differ.  At the end of the day, one planet, seven billion different worlds.
