“Always look on the bright side of life” Monty Python
For me, an optimist is someone that seems to naturally, or has learned to, accept life and focuses on the positive in the world. They are grateful and hopeful and confident about the future, expecting good things to happen when they have taken steps to create opportunities or control what they can e.g. their attitude.
“I always like to look on the optimistic side of life, but I am realistic enough to know that life is a complex matter.” Walt Disney
