fighting. fighting? fighting!

From Charlie Chaplin's film Limelight:

Ballerina: I can't stay here, causing you all this trouble.

Clown: I'm not complaining.

Ballerina: You should, I'm such a bore.
But it's not my fault. You would save my life.

Clown: Well, we all make mistakes!

Ballerina: I'm sorry.

Clown: You should be. A young girl like you wanting to throw your life away.
When you're my age, you'll want to hang on to it.

Ballerina: Why?

Clown: Well, at this stage of the game life gets to be a habit.

Ballerina: A hopeless one.

Clown: Then live without hope. Live for the moment.
There are still, there are still... There are still wonderful moments.

Ballerina:But if you've lost your health!

Clown: My dear, I was given up for dead six months ago, but I fought back. That's what you must do.

Ballerina: I'm tired of fighting.

Clown: Because you're fighting yourself. You won't give yourself a chance. But the fight for happiness is beautiful.
