Елена,
Это Ваше тоже через TextRanch пропущено?

Да 😁

Alex, ...life DOES IT

Elena, take care of IT.

Uly, thank you! What's the difference here between it and that?

Corrected.

Why don't hurry to take revenge?
And why the Present Simple?
This is why:

I wanna be around to pick up the pieces
When somebody breaks your heart,
Somebody twice as smart as I,
Somebody who will swear to be true
Like you used to do with me
Who'll leave you to learn that misery,
Love's company, wait and see.

I wanna be around to see how he does it
When he breaks your heart to bits,
Let's see if the puzzle fits so fine.
And that's when I'll discover
That revenge is sweet,
As I sit there applauding from a front row seat,
When somebody breaks your heart like you broke mine!

The song is available on my VK, enjoy listening!

Elena, the use of IT directs the listener back to the element "take revenge." Using THAT makes it sound like you're talking about something different.

Thank you, Uly. I don't catch it so far...(
Thank you, Alexander, for the lyrics )

Thanks for returning my dear like.
Elena,
As for It vs That, you can also see this: https://www.myhappyenglish.com/free-english-lesson/2014/01/22/it-vs-that-in-grammar-conversation-english-lesson/
Feel the difference:
You can do it - you are able/allowed to do it
You can't do that! - don't dare to do it!
