Edmond Rostand said this quote

...But...to sing,to dream, to smile, to walk, to be alone, be free,with a voice that stirs and an eye that still can see!To cock your hat to one side, when you pleaseat a yes, a no, to fight, or- make poetry!To work without a thought of fame or fortune,on that journey, that you dream of, to the moon!Never to write a line that's not your own...
