optimism, that core of reasonless hope

I am optimistic and confident in all that 
I do. I affirm only the best for myself and 
others. I am the creator of my life and my 
world. I meet daily challenges gracefully 
and with complete confidence. I fill my mind with
positive, nurturing, and healing thoughts.
