I Thought I Knew It All

Somewhere there's a reason why things go like they do
Somewhere there's a reason why some things just fall through
We don't always see them for what they really are
But I know there's a reason just can't see it from this far
Maybe I don't like it, but I have no choice
I know that somewhere, someone hears my voice
I thought I knew it all
I thought I had it made
How could it end this way?
I thought I knew
Somewhere there's a reason why things don't go my way
Somewhere there's a reason that I cannot explain
Just like the change of season, just may not be my turn
But I know there's a reason, the lesson's mine to learn
