Some would say it's insight.

If your going through a rough patch, Don't stop or slow down.
Cause infinity is impossible and you'll reach the end somehow,
And Sure you may get there it's just a red brick wall,
Thats too deep to go under and can't be climbed it's too tall,
But at least then you can learn to welcome your fate,
Adapting as an entity, learn to love the things you did hate.
Cause your lifes never been certain and it's flipped over before,
You were always one to smash in the window before checking the door,
But that don't mean you can't see the difference between right and wrong,
Each chapter of your life usually shorter than it is long,
So keep running on and sooner or later you'll find your out,
But when you get there then won't be the time for self-doubt,
Cause you never really know when that rough will come back,
So take the good with the bad, think of what you have not what you lack.
