Flex: "Mine" by Taylor Swift

You were in college working part time waiting tables
Left the small town, never looked back
I was a flight risk with a fear of falling
Wondering why we bother with love if it never lasts

Why does she shift time/verb tense?

What is the figurative  language used  for with  "flight risk"  and "fear of  falling"

I say can you believe it?
As we're lying on the couch
The moment I can see it
Yes, yes, I can see it now

Chorus
Do you remember we were sitting there by the water?
You put your arm around me for the first time
You made a rebel of a careless man's careful daughter
You are the best thing that's ever been mine

What does she mean, she's a "careless man's careful daughter?"

Flash forward and we're taking on the world together
And there's a drawer of my things at your place
You learn my secrets and you figure out why I'm guarded
You said we'll never make my parents' mistakes
But we got bills to pay
We got nothing figured out
When it was hard to take
Yes, yes, this is what I thought about

What is anaphora?

Chorus

Do you remember all the city lights on the water?
You saw me start to believe for the first time
You made a rebel of a careless man's careful daughter
You are the best thing that's ever been mine

Oh oh ohh
And I remember that fight, 2:30 a.m.
As everything was slipping right out of our hands
And I ran out crying and you followed me out into the streets
Braced myself for the goodbye
'Cause that's all I've ever known
And you took me by surprise
You said I'll ever leave you alone

How does modern plot structure vary from Shakespearean plot structure?

You said
I remember how we felt sitting by the water
And every time I look at you, it's like the first time
I fell in love with a careless man's careful daughter
She is the best thing that's ever been mine

(Hold on, make it last)
(Hold on, never turn back)
You made a rebel of a careless man's careful daughter
You are the best thing that's ever been mine
(Yes, yes), Do you believe it?
(Yes, yes), We're gonna make it now
(Yes, yes) and I can see it
I can see it now

How is Twelfth Night following this pattern?

Where are we in the development of the typical Shakespearean pattern?
