Linkin Park - In The End

It starts with one) One thing, I don't know why
It doesn't even matter how hard you try
Keep that in mind, I designed this rhyme
To explain in due time all I know

Time is a valuable thing
Watch it fly by as the pendulum swings
Watch it count down to the end of the day
The clock ticks life away, it's so unreal

Didn't look out below
Watch the time go right out the window
Tryin' to hold on, didn't even know
I wasted it all just to watch you go

I kept everything inside
And even though I tried, it all fell apart
What it meant to me will eventually be
A memory of a time when I tried so hard
