Saturn in the horoscope typically shows where and how we feel inadequate, and not good-enough. Saturn in the 11th house of friends and associates precisely shows that you are liable to feel uncomfortable around other people. With Saturn squaring Venus, you may also doubt your attractiveness and ability to form pleasant relationships. Then with Cancer rising, the crab is apt to retreat within her shell.
Of course, you are just as good as anybody else, but you are hard-wired to doubt that this is true.
Saturn is not all bad, though. It also rules beneficial qualities, like the capacity for self-discipline and hard work. Saturn trines your Mercury, your thinking and communicating abilities. Your Mercury is extra strong, in Virgo, the sign that it rules. It is well-placed in the third house of your day-to-day thinking and communicating abilities. If we put these together, you have the capacity of disciplined (Saturn) pragmatic (Virgo) thinking (Mercury.)
