The used figurative language is METAPHORE.
<span>We are
all heroes in our own ways. You are a hero the moment you came out of this
world. You sacrificed yourself sleeping late for your studies, giving time for
your friends and loving your family beyond their flaws. You are hero because
you have accepted yourself for who you are and you do things that you like and
didn’t do the thing you don’t like. You are a hero because in this world full
of masks, you emerged and became the distinctly you. And you have saved not
only yourself, as well as the people around you. </span>
I think you should put paratheses around it.
<em>basically im is used for not and here impossible means that anything which is not possible .. here main root or word is Possible because im is only a prefix .. this prefix 'im' changes the meaning of possible and makes it impossible :)</em>
