Every self-made person has a little bit of the arrogance and conceit of the character, the brilliant neurosurgeon, Dr. Stephen Strange:

    Lines from the characters (i’ve intentionally excised spoilers):

The Ancient One: [to Dr Strange] :

You’re a man looking at the world through a keyhole.
You’ve spent your life trying to widen it.                

             Your work saved the lives of thousands.
What if I told you that reality is one of many?

(after the guru shows how energy can be “wielded”):

Dr. Stephen Strange:

 

This doesn’t make any sense!

The Ancient One:

Not everything does.
Not everything has to.

Baron Mordo:

         Stephen Strange, might I offer you some advice?
Forget everything that you think you know.

                   Dr. Stephen Strange:

How do I get from here to there?

The Ancient One:

How did you become a doctor?

Dr. Stephen Strange:

Study and practice… Years of it.

[the Ancient One nods]

The Ancient One:

        You think you know how the world works.
You think this material universe is all there is.
What if I told you the reality you know is one of many?

The Ancient One:

Arrogance and fear still keep you from learning the simplest and most significant lesson of all .

Dr. Stephen Strange:

Which is…?

The Ancient One:

It’s not about you.
