Optimism is a tendency to believe that good things will always happen.
As an old saying goes, these girls who love laughing won't be in bad luck,which indicates that god favors most optimists whose expectations about life are positive automatically.
What impressed me most about this notion is a movie in which the main actor escaped the prison on his own and embrace new life even he was sentenced unfairly. To our amazement, he dug a underground path leading to exit by a small hammer for such a long time.
Obviously, he never lose heart while enduring much sorrow and torture .
There is a permanent faith in his mind that all the misfortunate are temporary and I will gain freedom again one day.
Optimism empower us to confront difficulties with patience and confidence , thereby the idealistic world we want will come naturally sooner or later.
