Meaning of the song fireworks!

Do you ever feel like a plastic bag  (do you ever feel useless & unwanted)
Drifting throught the wind
Wanting to start again  ( just start your life over)

Do you ever feel, feel so paper thin
Like a house of cards
One blow from caving in

Do you ever feel already buried deep  ( do you ever feel like no can here you or understand you?)
Six feet under scream
But no one seems to hear a thing  ( when you try to branch out nobody can here you)

Do you know that tehre's still a chance for you  ( I'm still considering you)
Cause there's a spark in you   ( because you're unique)

You just gotta ignite the light  ( build up your courage)
And let it shine   ( and show everyone the real you)
Just own the night     ( blow everyone away)
Like the Fourth of July       ( like the fireworks on the 4th of July how amazing they are)

Cause baby you're a firework     ( your unique and amazing with all of your colors.)
Come on show 'em what your worth      ( Show the world your worth something)
Make 'em go "Oh, oh, oh!"    (surprise them)
As you shoot across the sky-y-y

Baby you're a firework     (your a great person)
Come on let your colors burst    (show people who you are)
Make 'em go "Oh, oh, oh!"   (shock them)
You're gunna leave 'em fallin' down-own-own   ( you may be surprised of how much they like you back.)

You don't have to feel like a waste of space   ( dont feel like you dont deserve to live)
You're original, cannot be replaced         ( Nobodys like you)
If you only knew what the future holds    ( it may be bad now but your future will be way better)
After a hurricane comes a rainbow           ( everything always gets better)

Maybe you're reason why all the doors are closed       ( maybe you were the one holding yourself back.)
So you can open one that leads you to the perfect road      ( just keep driving you'll find the smoothest road)

Like a lightning bolt, your heart will blow      ( you will change instantly)
And when it's time, you'll know         ( you'll know when your changing)

You just gotta ignite the light       (Get out of your comfort zone)
And let it shine             ( just explode your personality and let it shine)
Just own the night             (be the life of the party)
Like the Fourth of July   

Cause baby you're a firework
Come on show 'em what your worth
Make 'em go "Oh, oh, oh!"
As you shoot across the sky-y-y

Baby you're a firework
Come on slet your colors burst
Make 'em go "Oh, oh, oh!"
You're gunna leave 'em fallin' down-own-own   ( your going to leave them surprised)

Boom, boom, boom
Even brighter than the moon, moon, moon
It's always been inside of you, you, you
And now it's time to let it through

Cause baby you're a firework
Come on show 'em what your worth
Make 'em go "Oh, oh, oh!"
As you shoot across the sky-y-y

Baby you're a firework
Come on slet your colors burst
Make 'em go "Oh, oh, oh!"
You're gunna leave 'em goin "Oh, oh, oh!"

Boom, boom, boom
Even brighter than the moon, moon, moon
Boom, boom, boom
Even brighter than the moon, moon, moon
