If your dreams don’t scare you, they’re not nearly big enough.
If your goals don’t inspire you, you need a loftier vision.
If your ambition doesn’t drive you to push yourself beyond your comfort zone, you need to aim higher.
So, I’ve set a couple of awesome, audacious running goals. I admit, I’m a little frightened, mostly inspired, and way outside comfortable. Sounds about right, then.
