Hero – Mariah Carey

There’s a hero
If you look inside your heart
You don’t have to be afraid
Of what you are
There’s an answer
If you reach into your soul
And the sorrow that you know
Will melt away

And then a hero comes along
With the strength to carry on
And you cast your fears aside
And you know you can survive
So when you feel like hope is gone
Look inside you and be strong
And you’ll finally see the truth
That a hero lies in you

It’s a long road
When you face the world alone
No one reaches out a hand
For you to hold
You can find love
If you search within yourself
And the emptiness you felt
Will disappear

Lord knows
Dreams are hard to follow
But don’t let anyone
Tear them away
Hold on
There will be tomorrow
In time
You’ll find the way

Rascal Flatts – Things That Matter

Sometimes he lets that boss get

In his head

He can’t see passed that mountain

Of deadlines on his desk

Five o’clock, he’s the last one

Out of the gate

And he gets cut off, flipped off, ticked off

Out on the interstate

And he wonders why this world won’t

Leave him alone

Til he hears that little voice holler

Daddy’s home


Things that matter

Things that don’t


She’s held on to that grudge

All her life

And thirty years of anger

Since her dad walked out that night

She thinks of all the moments

That he’s missed

All the birthdays, ballets, first dates

It seems too much to forget

She gets that call that said he

Don’t have long

She walks in, he starts crying

The past is gone


Things that matter

Things that don’t


Time ain’t on our side

Don’t wanna leave this world

With why didn’t I, why didn’t I

Yeah, why didn’t I


Sometimes I take on this world

By myself

Thinkin’ I got all the answers

Don’t need anybody’s help

When God was right there waiting

For me all along

To fall down on my knees

Surrender all


Things that matter, things that don’t

Things that matter, things that don’t
