"Little by Little" Oasis

I saw this track on Oz TV on the ABC RAGE program and was caught up in what is pretty much Oasis at their annoying best!! The 'publicity tart' Gallagher brothers put together some brilliant pop tunes from time to time and this is an interesting exploration... from their 2002 album 'Heathen Chemistry.' I think it's great that the songs of theirs I find most poignant are sung by Noel and not Liam. I note this clip includes the signpost for 'Heathen Street.' I like the image that "Y'know I didn't mean what I just said, But my god woke up on the wrong side of his bed."
Is the song a general reflection on mortality? Is it about the breakdown of Noel's then relationship and divorce? Is it written to his daughter in the light of that?

"Little by Little"
We the people fight for our existence
We don't claim to be perfect but we're free
We dream our dreams alone with no resistance
Fading like the stars we wish to be

Y'know I didn't mean
What I just said
But my god woke up on the wrong side of his bed
And it just don't matter now

Cause little by little
We gave you everything you ever dreamed of
Little by little
The wills of your life have slowly fallen off
Little by little
You have to give it all in all your life
And all the time I just ask myself why
You're really here

Dream perfection has to be imperfect
I know that that sounds foolish but it's true
The day has come and now you have to accept
The life inside your head we give to you

No I didn't mean
What I just said
But my god woke up on the wrong side of his bed
And it just don't matter now

Cause little by little
We gave you everything you ever dreamed of
Little by little
The wheels of your life have slowly fallen off
Little by little
You have to give it all in all your life
And all the time I just ask myself why
You're really here

(Hey!)
Little by little
We gave you everything you ever dreamed of
Little by little
The wills of your life have slowly fallen off
Little by little
You have to give it all in all your life
And all the time I just ask myself why
You're really here

Why am I really here?
Why am I really here?
