“Training will only get you so far. If you don't believe in your training, you will sabotage yourself. If you're driven by dense, aggressive, and forceful emotions, it’s hard to feel yourself being pulled, easily towards your goal. But when you tap into the good emotions that you set out to accomplish in the first place (which means that you have to do the work to know what those are when you begin) you can make extraordinary leaps in performance.”
― Andrew Snow, Run Elite: Train and Think Like the Greatest Distance Runners of All Time
