Maturity might be code for those who only believe in the rational world.
But purely rational thinking people don’t have much fun.
Rational doesn't know how to be silly.
Rational is into thinking all the time and doesn't know how to enjoy being a little crazy and joyful.
Relationships need new and different experiences that keep couples growing together... being a little child like… makes for excitement.
And real happiness comes from inside.
Happiness is not what the outer world brings... it's what we view the world through.
And the new rage of "Positive Psychology" means seeing the world through the light of positive thinking... that means you have to have a positive frame of mind... not just a rational mind.
A positive mind can have fun and be happy… from the inside out.
As it says in Spiritual Text -- "Come unto me as a child"
