“For most of history, man has had to fight nature to survive; in this century he is beginning to realize that, in order to survive, he must protect it.”

Each misfortune you encounter will carry in it the seed of tomorrows good luck.

You must welcome change as the rule but not as your ruler.

Yesterday is history. Tomorrow is a mystery. And today? Today is a gift. That is why we call it the present.

No yesterdays are ever wasted for those who give themselves to today.

Don't ruin the present with the ruined past.

All I can say about life is, Oh God, enjoy it!

I never think of the future. It comes soon enough.
