Greatest Mistake lyrics

I treated you wrong and that ain't right
It took me too long to realize
that the only thing that matters is right now

Because no one knows if the soul exists
They don't know where it goes
when it gets too hard to lift
I gotta be part of
the greatest mistake called love
[ Lyrics from: http://www.lyricsmode.com/lyrics/0-9/54_40/greatest_mistake.html ]
Forgetting my best to treat you kind
I shouldn't have let you read my mind
And that the only thing that matters is right now

Because no one knows how the heart can feel
They don't know where it goes
when it gets as cold as steel
I gotta be a part of
The greatest mistake called love
La La
Here's to tommorow and old yesterdays
But no taste is finer than today
