If the answer is 'no one' other than yourself, you're either:
A. Not looking hard enough past the image in the mirror or;
B. Not pushing yourself far enough.
Can you think of at least 1 friend 'back home' who would say this to you, in all honesty? If not, are you pushing yourself far enough now?
Are you willing to push yourself farther?
Who do you owe it to? If the answer is 'myself' it's gonna be a long and lonely road.
