Heartless - So Unreal lyrics

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

One thing, I don't know why
It doesn't even matter how hard you try (try [?x])
It starts with one

In the end [2x]

One thing, I don't know why
It doesn't even matter how hard you try (try [?x])

I don't know why

One thing, I don't know why
It doesn't even matter how hard you try (try [?x])
It starts with one
