"I can"

Every time you begin running, you are posed with a question. Whether it be a jog around the neighborhood or the last lap of the 400.. life is testing you. No matter your reasons are, or your goals or expectations, those little voices inside your head, they're asking you how badly you want it. At that point you can either tell yourself you can or you can't. You can give up or fight like hell. You decide to tell them you're a fighter, they say: prove it.
Have a love-hate relationship with those little voices. You don't realize how often they test you in everyday life... making you feel you're in way over your head. Making you believe you'll never meet what's expected. They want you to believe you're worthless. They want you to PROVE it.
At the end of the day, those little voices triggered something so much stronger, so much more indestructible than the "I can't", they powered the "I can".
