natural American English - Rocky Balboa 2006
I´ll tell you something you already know.
The world ain´t all sunshine and rainbows.
It´s a very mean and nasty place.
And I don´t care how tough you are,
it Will beat you to your knees
and keep you there permanently if you let it.
You, me, or nobody is gonna hit as hard as life.
But it ain´t about how hard you hit.
It´s about how hard you can get hit and keep movin´ forward.
How much you can take and keep movin´forward.
That´s how winnin´is done!
If you know what you´re worth, get what you´re worth,
But you gotta be willin´to take the hits and not pointin´fingers,
sayin´ you ain´t where you wanna be because of him or her or anybody!
Cowards do that, and that ain´t you!
You´re better than that!

This feels more like a Southern accent, but I'm from the West so I tried to stick to my native accent as much as possible.
