You learn from each other.  This is why Source divided and multiplied itself.  How else to experience, to grow, to enjoy, and then to do it all over again and again and again?  How else to know love and all of its many aspects, and in the case of your Earth School, the billions of nuances of Life?  Do not worry if others are like you or not like you or if others like you or do not like you.  Be yourself.  Just BE, which does not mean to sit and gaze at your navel at all times.  Gazing is good, but gaze about you at others and appreciate what they do and how they do what they do.  That is part of the experience.  To appreciate something does not make it right or wrong, however.  It simply means to make note of and then to compare it with one’s own experiences for the purpose of then growing and changing … or not.  And that is Life.  Is it not glorious?
