What is the name of the song?

Question

I have tried to find a song in which probably were following words:
I knew you had to live...
Sometimes it's hard to make up your mind...
[Chorus]
Change, change my world, change my mind.........

if you know the singer or name of this song, please, put me on notice.

i've seen you walking trough an emptying space
then i knew you had to live
sometimes it's hard to make up your mind
and it's hard to let it be
Then again ..... to save the words
soul is clear for anyone .....
it's like looking through a sliding door
when nothing seems to save the same
if you don't care ..... look by one
to never known from where you came
now you're gone
right now and here
leaving me to find a number ....
So you change, change my mind,
change my world
change the ground of walking on
to change the sun
to change the moon
change the....life

something like this...

Well Bobby had everything
He thought he'd ever need
A fancy new car
And a master's degree
Still he's feelin lost
With no purpose in life
And nothing seems to fill the empty space inside
He sees an ad on late night TV
It says "Change your kids' life with just a couple hours a week"
Normally he'd keep clicking
Just surfin around
But something makes him stop and write that number down
Oh it's amazing
How love changes everything..

Well Sarah does her best just to keep the faith
But ever since he left
It's hard to find the strength
She wipes the tear from her eye
As she puts the groceries on the shelf
Cuz after dinner, baths and homework
There's no time for herself
Two jobs, two kids
Too tired to fight
No money, no romance
No end in sight
Just when she thinks she can't go on
She sees a painting on the fridge that says
"I Love You Mom"
Oh it's amazing
How love changes everything

Well I know we've got problems(I know we got problems)
We gotta figure out baby(We gotta figure out baby)
And I know we haven't been talkin
Or touchin much lately
But I know this love(I know this love)
Has got alotta life left in it(Has got alotta life left in it)
So let me hold you close
I don't wanna let you go
Baby let me know we won't wait another minute

It can change the world
It can change your mind
It can change your tire in the middle of the night
It can change your name
It can change your heart
It can change your tune
It can change your life
Love changes everything...
