Show me somebody who is always smiling, always cheerful, always optimistic, and I will show you somebody who hasn't the faintest idea what the heck is really going on.
I would feel more optimistic about a bright future for man if he spent less time proving that he can outwit Nature and more time tasting her sweetness and respecting her seniority.
My friends, love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful and optimistic. And we’ll change the world.
