My Current Theme Song

I know I cannot be the only person on the planet who has their own internal soundtrack. :-) If I am, just play along with me, okay? Every so often, I hear a song the grabs me by my emotions and fills me with motivation and inspiration to be my best me. I consider that my "theme song". Right now, my theme song is Katy Perry's "Firework".

Lyrics from http://www.directlyrics.com/katy-perry-firework-lyrics.html

Do you ever feel like a plastic bag
Drifting throught the wind
Wanting to start again

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
Six feet under scream
But no one seems to hear a thing

Do you know that there's still a chance for you
Cause there's a spark in you

You just gotta ignite the light
And let it shine
Just own the night
Like the Fourth of July

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

Baby you're a firework
Come on let your colors burst
Make 'em go "Oh, oh, oh!"
You're gunna leave 'em fallin' down-own-own

You don't have to feel like a waste of space
You're original, cannot be replaced
If you only knew what the future holds
After a hurricane comes a rainbow

Maybe you're reason why all the doors are closed
So you could open one that leads you to the perfect road

Like a lightning bolt, your heart will blow
And when it's time, you'll know

You just gotta ignite the light
And let it shine
Just own the night
Like the Fourth of July

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

Baby you're a firework
Come on let your colors burst
Make 'em go "Oh, oh, oh!"
You're gonna leave 'em all in awe-awe-awe"

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 gonna leave 'em all in awe-awe-awe

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