Churchill’s classic black dog statement is as follows:

1. Success does not matter, failure is not fatal. The courage to continue moving forward is the most valuable thing.

2. Pessimists see difficulties in every opportunity. Optimists see opportunity in every difficulty.

3. Courage is the ability to stand up and talk. Courage is also the ability to sit down and listen.

4. I never worry about taking action, I only worry about not taking any action.

5. We are with Europe, but never belong to Europe.

6. All I can offer is blood, toil, sweat and tears.

7. As far into the past as you can see, you can move into the future.

8. There are no permanent friends or permanent enemies in the world, only eternal interests.

9. Never, never, never give up!

10. I would rather lose an India than lose a Shakespeare.

The movie "Darkest Hour" tells the heroic deeds of Churchill who led Britain through the darkness and out of the crisis during World War II.

As British Prime Minister, Churchill not only had to resist the invasion of German Nazi forces, but also faced a group of unprepared people and a king who doubted himself.

He must resist double pressure to face the next darkest moment.

In 1940, the speech delivered in the House of Commons of the British Parliament was unprecedented and inspired countless people in Britain and the Allied Powers.

People believe that it was Churchill’s firm belief and fighting courage that ultimately won the Battle of Dunkirk and led Britain out of the crisis.

However, what people don’t know is that behind this perseverance and courage, he has also experienced bleak adversity and suffered from despair.
