Enthusiasm is the yeast that makes your hopes shine to the stars.

There is no medicine like hope, no incentive so great, and no tonic so powerful as expectation of something better tomorrow.

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

Helplessness induces hopelessness, and history attests that loss of hope and not loss of lives is what decides the issue of war.

Tragedy is restful: and the reason is that hope, that foul, deceitful thing, has no part in it.

It is easy to say we have come a long way, but we still have a long way to go… But I still remain hopeful.

I hope to build a reputation as a science-fiction writer. That's the pitch. We'll see.

Optimism Is The Faith That Leads To Achievement. Nothing Can Be Done Without Hope And Confidence.
