A member of a U, not a circle

 I read an article today, which corresponds to my thinking of late.  I work with a woman who forever talks about herself as a victim.  I am absolutely not going to be like her.  I recognize that my situation in life is my own doing.  Consequently I can change my life circumstances and this brings me joy and hope. Now a circle of friends, because it is closed, excludes people. A horseshoe, and I so enjoy working with horses, or the letter U is open-ending, in process, growing... Everyone is welcome, differences are appreciated.  Difference is the spice of life.
