Less than perfect

I know a song
ain't good enough
to let you know how I feel
I'll sing it hard
I'll sing it sweet
to let you know that it's real
If I change my attitude
maybe I can conquer you
completely
All the things I say and do
everything I learn from you
defeats me
And let you down
I let you down
I know it's wrong
to blame the past
for everything that I do
I fool the world
most of the time
but there's no fooling you
If I change my attitude
maybe I can conquer you
completely
Everything I say and do
all I learn from you
defeat me
And let you down
I let you down
What you see
ain't always what you get
No matter how clear it seems
One minute lovers
...then the next...
