There is magic in misery. Just ask any runner.
Don't confuse comfort with happiness.
The only one who can tell you "You can't" is you. And you don't have to listen.-Nike
I run because it always takes me where I want to go.
Sometimes you've got to go through hell to get to heaven.
I never feel more alive than when I'm in great pain, struggling against insurmountable odds and untold adversity. Hardship? Suffering? Bring it!
