I was born right-handed.
I spent 5 decades teaching myself to fluently use my left hand in playing my beloved alto saxophone.
I was born optimistic.
Life's taught me hard, hard, super-hard lessons in the utter importance of being fluent with using the non-optimistic aspect of my inner-self.
Optimism is my deep preference.
Survival is my deepest preference.
Thus, of necessity, I like to think the way of TAO: "The Ambidextrous Optimist".
