Call me corny, but.

Rocky Balboa: The world ain't all sunshine and rainbows. It is a very mean and nasty place It will beat you to your knees and keep you there permanently if you let it. You, me or nobody is going to hit as hard as life. But it ain't about how hard you hit, it is about how hard you can get hit and keep moving forward, how much can you take and keep moving forward. That's how winning is done!
