英语作文：Hope for the best and prepare for the worst

As a human being,we should be optimistic so as lead a better life.So whenever we are in face of anything,we should see it in the bright light.As we do so,we will find ourselves filled with confidence when encountering a difficulty,with energy when meeting a challenge,and with enthusiasm when competing with a rival.Why can we act like that?Because we have hope,and we hope that the result will always be the best one.But does it mean that we are optimistic blindly?The answer is absolutely “no”.Only when we have done enough preparations for the worst situation we will be in,can we have the hope.As Chinese old saying goes,” Everything goes well if prepared,otherwise goes wrong.” When we have done what we should have done in advance,what else should we worry about?
In a word,to hope for the best and to prepare for the worst is an optimistic and wise person should do.
