Life wouldn't be possible if we did not all have hope. how true os this statement

This is very true.

Explanation:

If not even a speck of us had hopes then we would not have anything that we had today. Everything would be dark and glum. People would be hurting themselves and others left and right more than what they are doing now. And there would be no police officers to stop them. Think of it as a zombie apocalypse. Except without the brains. Just lifeless humans wandering around.
