about getting hit and keep moving forward

"The world aint 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 and nobody is gonna hit as hard as life. But it aint about how hard you hit, its about how hard you can get hit and keep moving forward. How much you can take and keep moving forward. That's how winning is done! If you know what you're worth than get out and get what you're worth but you've got to be willing to take the hits and not pointing fingers saying you aint what you wanna be because of him or her or anybody. Cowards do that and that aint you! You're better than that" (Rocky Balboa)
