Don't forget the "fuck-ups." No matter how you prepare, no matter your intention, your focus, your determination, little "fuck-ups" like ornery gremlins can crawl out of any corner and throw little stones in your path. You will stumble, you will waver, you will sweat, you will curse, you will be befuddled, thrown off and frustrated. That is just the way. BUT. You must carry on. Damn the torpedos. Yes. You must.
