"People think a soul mate is your perfect fit, and that's what everyone wants. But a true soul mate is a mirror, the person who shows you everything that's holding you back, the person who brings you to your own attention so you can change your life... they tear down your walls...But to live with a soul mate forever? Nah..."
-Eat, Pray, Love

There is more to this quote, but I will add it in later. To a certain extent, I agree with what it says.
